I want to grow up to be a kid.

If you don't have a struggle uphill the journey down the slope won't be as fun.
Knowing that you can make the journey up gives the courage to stick your hand in the dirt. again.

The trick with age might be to feel like a kid every second you-

-Feel like your knees are giving out

-You ain't good enough for the world

-You can't see well enough

-You regret more than you reminisce

The trick with age might be to feel like a kid every second.
