Drawing
Drawing helps you see. It does not matter if you draw well, the visual benefit is the same. Go to this web page ; read page 1, draw the figures on page 1. Second try to draw the 4 figures on page 3. You need not try the Escher one at the bottom. These pages were created by Thomas Leavett who graduated several years ago.
