Abstract understanding doesn't mean arbitrary sloshing and messing. Abstract art is controlled visual magic based on laws and methodology. Abstraction generally involves implication, suggestion and mystery rather that obvious description. Like a good poem, a good abstraction attacks your feelings before your understanding. Abstraction within realism adds zest and excitement to otherwise dull subject matter. Abstract understanding takes time and patience.

In painting you cover up your sins and everyone thinks you're naturally talented.

Waiting for inspiration is for amateurs; professionals get to work.

Whatever you do, don't let your system run you.

A drawing a day keeps the cobwebs away.

Artists with serious aspirations need to be left alone to follow the course of their own imagination.

No matter what your disciplines, you need your own personal lists.
