I've been learning to draw lately and I was having some serious "getting started" issues every time. For me the trick was to not go "I will now practice drawing" but to go "I will now hold a pencil and browse through my old drawings". It ends me up holding a pencil and looking at a blank page.

I know it ends up with me drawing anyways every time and yet lying to myself that I'm not intending to draw works wonders.
