What should you be doing when you’re young? One resource that young people have over everyone else is time. Which means that whatever you do, do something that leverages time to your advantage.
One way to leverage is the snowball effect. The snowball effect is when you let a small snowball* roll down a mountain.The snowball gets bigger; slowly at first. But then it picks up on size which gives it more surface area. This in turn causes the ball to gain even more size. The gains compound into even bigger gains.
The younger you are, the higher you are on a mountain. Every day that passes, you get a little lower and in return makes the potential end result exponentially weaker. Every day that passes, you loosen your grip on the power of time. The sooner you begin to roll the snowball, the bigger it will be in the end.
What are snowballs though? Snowballs are skills that will stay relevant to you all your life. Everyone will have their own definition of a snowball. Writing, socializing, programming, playing the guitar, your athletic ability; these are all viable snowballs. But for everyone, it will be different. The only thing that anybody should be focusing on at a young age is which snowball they want to roll. The next thing they should do is to put razor focus onto it.
You can only focus on one ball at a time. If you switch your focus from a snowball, it doesn’t die, it just freezes in place until you put your focus back. So imagine you roll two balls down a mountain at the same time. You split the focus 50/50 and whenever you focus on one, the other is frozen in place. Compare the sizes at the end to someone who focused only on a single ball, and the difference will be tremendous. Much bigger than 2x the size, assuming the mountain is tall enough.
So choose your snowball wisely because if you keep changing your mind it will become weak in the end. But also choose quickly, you are getting lower on the mountain everyday. After you let go, keep putting your effort in. Allow the skill to flourish. Progress will probably look slow in the beginning, but just know that it’ll get bigger the longer you keep focusing. Just keep going until it gets fun to see how fast it’s growing.
*Snowballs probably don’t work this way in reality
