Go for it now. The future is promised to no one.
You never know what motivates you.
I can, therefore I am.
The dog that trots about finds a bone.
After a storm comes a calm.
Expect problems and eat them for breakfast.
What you do today can improve all your tomorrows.
Problems are not stop signs, they are guidelines.
Be thine own palace, or the world's thy jail.
It's always too early to quit.
The whole essence of good drawing - and of good thinking, perhaps - is to work a subject down to the simplest form possible and still have it believable for what it is meant to be.
