1) Walk away
2) Force it
Today I am forcing it by doodling these scenes in my notebook, scenes from the house where I grew up. The other day I realized how many trivial details I can still remember of a home last visited ten years ago, and wondered how awful it would be if later on in life I'd forgotten all of them. Of course, brains will fill in any memory gaps with fabricated details, so there's no telling how removed from reality these doodles will get as time passes.
