Yes! In fact, my husband has a theory that it's a requirement for me to be truly productive. I love giving myself challenges, and if I don't have them I tend to lose interest pretty fast. This past week I was working on a writing contest and deciding I'd had enough of writing and tweaking about 24 hours before the deadline. There was still one article out of 20 I could write, but I didn't think I could do better than the ones that were already there. I also had about a half-dozen articles that could use a little tweaking, but didn't think I'd get that done either. My husband chimed in with, "Well, so you have 24 hours to do a really good article and get your tweaking done. I know you can do it, you don't need a lot of time to get something really good. I look forward to reading them when I get home from work." Sooooo with this artificially-applied pressure, I got it done and probably boosted my chances of winning a few times over, and ended up with articles I liked much better than I expected. On client projects I also tend to dabble a little bit here and there until the last day or two before the deadline, then start churning out the work. Several of these clients prefer delivery on each piece as it's finished, and quite a few of those have commented that they like the last ones best.
