I keep a log of most of my decisions. I didn’t like a TV series about ghosts? I take a note, and I’ll stay away from spooky ectoplasmic shows in the future. Did I enjoy a crafty show on pottery? I’ll make sure I’ll watch the next season for sure. The only difference between screwing around and science is writin We can afford to make bad decisions; what we can’t afford is learning nothing from them.
