4 Things You Should Learn Today That'll Be Useful the Rest of Your Life

Simple, effective, consistent tips that will improve your productivity, communication skills, and more.

In the late 1960s, my grandmother began choking on a steak at a wedding party. She fell to the floor unconscious, and after three days in a coma, passed away. Nobody at the wedding party knew the Heimlich maneuver (it wasn’t taught very often). And because of that, I never got to meet my grandmother.

Today, most people know these basic skills and lessons that could change someone’s life. There are other, unusual, deceptively simple things that deliver profound value — with very little effort.

1. Leverage an unusual productivity principle

The Pareto principle is a far-reaching statistical phenomenon.

It’s anchored in an 80:20 system. For example, in healthcare, 80% of costs stem from roughly 20% of patients. In sales, 20% of products often constitute 80% of sales volume.

Even Microsoft uses the Pareto principle: they realized that solving the top 20% of commonly reported bugs stopped Windows from crashing 80% of the time.

The Pareto principle is the science behind, “A little bit goes a long way.” It’s why students who open their books for even 15–20 minutes, usually do far better than those who don’t study at all.

In time crunches, our brain is wired to be remarkably efficient and good at prioritizing. Examples of the Pareto principle could fill a dozen pages, and you can use one today.

The trick: When you have a task — be it cleaning, coding, writing, working — ask yourself, “What 20% of this can I do that will deliver the majority of the results?”

For example, with cleaning: sweeping areas of your home with the highest use (where people walk or eat most) delivers the most efficient use of your time. Think small — as it relates to big.

One of the pitfalls people fall into is assuming that doing seven or eight small tasks is being productive when they don’t actually move the needle. Try to focus on the one or two things that will have the highest impact. I’ll give you a hint: they are generally the things you want to avoid. Knuckle down and do them.

Heck, I’ve even inverted this principle with my diet. I found that if I can stick to a perfect macro-micro nutrient diet for 80% of the time, it gives me room to indulge a little in that other 20%. But that doesn’t mean I can go into a full binge session.

2. Live within an “open network”

When I watch movies, I see so much diversity. A bank heist crew always has a few white guys, a black guy, maybe an Asian guy, all working together. Superhero teams have a broad mix of people that gives every group a “seat at the table”.

Yet when I sit down for lunch at literally any office or public place, it feels so tribal. One table is mostly white dudes, another is Asian women.

This relates to homophily, a common phenomenon where we sort ourselves into similar groups, and our network gets increasingly closed:

The further to the left you are on the above chart, the greater your odds of success. It means you are surrounded by a varied and open network of people. Putting all moral platitudes aside, diversity is literally good for your life.

You are exposed to ideas different than your own, unconventional thinking, and a plethora of career paths. Open networks reduce bias and improve decision-making.

Conversely, a closed network occurs in these four steps:

Consider this: Within 10 years of graduation, a majority of people won’t work in the area they majored in.

It pays to have a wide group of friends, to help you see what else is out there, to test your own assumptions. People living in open networks innovate and have higher lifetime earnings than those who don’t.

3. How to be an email assassin (and communicator)

Oddly, the most useful class in my MBA program wasn’t a finance or operations class. It was a business writing course. We sat in the classroom, groaning, thinking, “Damn. How did I not know this?”

In our most entertaining homework assignment, we each brought in the sloppiest work emails we’ve seen.

Many of my classmates worked at elite companies, yet still scraped together horrifically written emails, full of typos, cursing, incoherent wandering. I wondered how some of these people got into Ivy League schools.

My example was from a coworker who used giant barbie-font, bolded in pink, size 30, that could only fit five words per line in the body of the email.

I remember reading those emails, thinking, “I don’t know what this email is about. But I hate everything about it.”

There’s a very simple trick to writing good emails and it applies to verbal communication: remember that most people are busy and generally motivated by self-interest.

• Front Load your message. Include your intentions, in very clear terms in the first sentence, “I’m writing because my refund wasn’t processed.”

• Be specific in your subject line.

• If you need to persuade, use Logos(logic), Pathos(emotion), Ethos(credibility), in varying degrees depending on the context.

If it's a client or prospect, it should definitely be personalized. Email excellence carries the infrastructure of good communication. Don’t be a sloppy emailer. Be clear and get to the point.

4. Improving the back issues

When I took my first office job, there was an initial shock to being seated for eight to nine hours a day in front of a computer screen.

I noticed my posture became terrible over time. And this coincided with consistent back pain that began to interrupt my quality of life. This problem is quite common. One study found that 70.5% of respondents had neck or back pain at some point within the last month. Our bodies are still programmed as hunter gatherers, hence this sedentary lifestyle has been terrible for our health.

Finally, I went and saw a chiropractor who began adjusting me and also gave me exercises to strengthen my core.

I’ll share one of best practices he taught me, that I use to this day. This might sound weird, but—pretend there are lasers coming out of your nipples. Anytime you are talking to someone, those lasers should be pointed directly at a person's face. When I do this, it causes my shoulder blades to pull back, and my chest to point up. My chin raises more. It takes the pressure off of my lower back and helps me develop my core strength, which holds me upright.

If you are having back pain, one of the best things you can do is work on your posture. Additionally, going to the gym and practicing weight training works wonders for back pain. Try to avoid activities that are high impact, such as running.

Recap for memory: four things you can do to better your life

1. Have friends of diverse backgrounds. It improves cognition, lifetime earnings, and contentment.

2. Identify the steps where 20% will deliver 80% of your desired results. 80:20 applies to a shockingly large number of things in life.

3. Focus on improving your posture. Imagine lasers coming out of your chest. They should point at a person's face when you're standing.

4. Stop writing sloppy emails. Be to the point, specific, and persuasive when need be (use appeals to logic, emotion, credibility). Don’t use huge barbie font.
