For #1, yeah I do. If I'm working on more routine/boilerplatey parts I might go a little longer without running, but it's pretty important to me to verify that each bit is working as expected before moving on. It's easy to wind up in a mess if I'm operating on the assumption that what's been written so far all works.

For #2, yeah that's true, but for me less visible improvements are gratifying, because not only is the thing being rewritten being improved, but I can also apply learnings to other projects that make rewriting them less necessary. Also, it just bugs me when there's reasonable obtainable improvements in optimization, flexibility, etc that I've left on the table… feels like I left the job half-done which isn't a great feeling.
