Give up on projects you intended to carry out, that really have promise.
I can't recall every instance of it, at the moment, but I've seen nearly all of you give up on something that really seems to have promise/potential, at least once.
Not that it's a problem, really. Most times (in fact, almost always), it entails things that are not lost forever, and can be returned to at a later date. Still, sometimes, when I see it happen, it is a tad disappointing.
