One can never study nature too much and too hard

I am risking my life for my work, and half my reason has gone.

We are surrounded by poetry on all sides.

That I was not suited to commerce or academic study in no way proves that I should also be unfit to be a painter.

The only time I feel alive is when I'm painting.

Only when I fall do I get up again.

... life is too short to do the whole.
