There is one thing that you can do, your way, better than anyone else in the world. I don’t know what your thing is, but you do. If you don’t know what it is you may want to take the time to think about it because your effect on the world depends on it.
We all spend time doing things that other people also do; much of this time is spent when we’re doing something in a group — practice with our team, at work doing some menial tasks, commenting on current events. The time we spend alone, doing that one thing that we do best, is what separates us from everyone else. That time is what will be the difference-maker when you’re laying on your deathbed, saying your last goodbyes to whomever cares enough to be there.
Carve out as much of it as you can and no matter the amount, make the most of it.
