I have learned many things in my life. Here are four things I would like to teach the world:

Attitude is everything

10% of your life consists of things you willed or brought about. Don't sweat that small stuff. 90% is all that you cannot control, the stuff that just happens to you. How will you deal with those things? How will you react? What will you learn? The key to these questions is the attitude. That's great news, in a way.

No matter your level of formal education, no matter how far you think you got in your life with your career or relationships. None of these things (the 10%, remember?) matter if you have not fostered three most important attitudes. Both can be infinitely scaled. Their power is limitless if you learn how to attend to them.

First is gratitude, the attitude directed towards appreciating anything and anyone. The ability to assign a value to something that others overlook. The deep, bottomless wellspring of being thankful for your health, your family, your job, anything. This is the secret to true richness. It never runs out. And best: it is not a scarce resource, unlike any other resource in the world.

Always return kindness

You may wonder if this is not just one of those values I talked about above, and I would tend to agree if it were not for the fact that kindness is not just a value. It is something so enormously important I would place it in a category of its own. Whatever your values, whatever you do with yourself, never forget to be kind.

Let me rephrase this since we all forget a lot of the time (we are human): try not to forget, and when you eventually do, make it up by returning to kindness. Don't ask why. If you have to the reason is this: because it's the right thing to do.

Humility

Second is levity or humility, the attitude of not taking yourself too seriously. Never forget where you came from. Never forget what you are: just human. No matter how high you fly or how low you fall, it all just seems so much easier if you tread lightly if you remember not to take yourself and those many projects of yours too important to the point of agonizing about them.

It is fine to strive and seek. But this too shall pass. Don't forget that in your darkest hour and it will set you free.

Resilience

Resilience is the attitude to weather anything from the gentlest breeze to the strongest gale threatening to derail or break you on your journey. Some call it growing a thick skin, a tough hide, robustness or fortitude. No matter what you call it, foster it because you have no idea what people are capable of surviving.

The world is not necessarily cruel by definition, but it can be cruel by ignorance, by the apathy of nature, by forces so large they can toss you around like a speck of dust to make you know your place in the scheme of things. Those times can hurt. A lot.

I wouldn't lie as you will likely have your fair share of hurt even if you did nothing to deserve it. For those times, I wish for you to have the resilience to suck it up and then get back to work.
