Does anyone else feel that posts like these are vapid? Not because the advice is obvious or rehashed. I actually think it's great to reiterate important points in order to reinforce them. The reason I feel these points are vapid is because they essentially are things we already know we shouldn't do, without a real concourse of how to truly sidestep them. I mean, a whole book can be written on how not to cry over spilled milk. So is a paragraph of empty emphasis effectual?
