Here's a great quote by Chuck Close that helped me put an end to artists block for good.
"The advice I like to give young artists, or really anybody who'll listen to me, is not to wait around for inspiration.
Inspiration is for amateurs;
the rest of us just show up and get to work. If you wait around for the clouds to part and a bolt of lightning to strike you in the brain, you are not going to make an awful lot of work.
All the best ideas come out of the process; they come out of the work itself.
Things occur to you.
If you're sitting around trying to dream up a great art idea, you can sit there a long time before anything happens.
But if you just get to work, something will occur to you and something else will occur to you and something else that you reject will push you in another direction.
Inspiration is absolutely unnecessary and somehow deceptive.
You feel like you need this great idea before you can get down to work, and I find that's almost never the case."
There is no such thing as artist block.
You can always draw you just may not feel inspired.
Inspiration is for amateurs. The rest of us get to work.
If you wait for a lightning bolt of inspiration to hit you you're not going to get much done.
Often times a tiny idea blows up into a huge idea.
Inspiration comes from the process most times.
There's always time to contemplate my reasons...
while you draw.
There's time to figure it all out...
as you draw.
And if you're still stuck practice drawing hands.
Just don't stop. Ever.
