Do it now.

So now you're in your twenties
Asking yourself when time happened
When you became an adult,
responsible for your own life.
Scared before the forever-feared thirties.
The same way you feel now,
You'll feel at sixty
asking yourself what would have happened
"If".
So, figure out what the hell it is
that you want to do and do it. Now. Here.
You won't regret it.
