Lose your inhibitions about drawing and just do it.

dont wait for next minute, next hour, next day, next week, next year, just do it if you want to do it...

I just have work to do; I just do it.

If you want to really learn your playbook, you just do it.

There's doubt in trying.
Just do it or stop thinking.

Just do it... that's all... no matter what, when and where... but just do it.
