There is a lot of bad advice about being happy.
Here is some good advice:
Get used to not getting everything you want.
There will always be another dream, a bigger vision, a new toy, or a fresh style to pursue.
Something that rich people complain about is still feeling a sense of missing something; of needing more.
That is just how human brains are wired.
Just the same as we will always get hungry, and thirsty, and tired.
We haven’t got the time to be great at everything. We can’t solve all the problems in the world or have all the things or even try everything.
So we must be content with immersing ourselves in the handful of pursuits that make us most happy — and get used to not having the rest.
