God does not require you to follow His leadings on blind trust. Behold the evidence of an invisible intelligence pervading everything, even your own mind and body.
Art is not what you see, but what you make others see.
It is all very well to copy what one sees, but it is far better to draw what one now only sees in one's memory. That is a transformation in which imagination collaborates with memory.
Painting is easy when you don't know how, but very difficult when you do.
