I trash and restart sketches that took a few minutes to do at most. It's very rare for me to get more than an hour or two in and discard it, I've explored and found a solid foundation long before I put that much work in.

If I was working in a studio environment there's the risk of things like "I spent a couple weeks painting that bg and animating that scene and it was absolutely gorgeous but it got cut when the we took a good hard look at the remaining budget and total runtime and cut the entire sequence it was part of" but that's another matter.

The Draw 50 process is solid. The classical techniques I learnt in training for animation are similar.
