I feel this is good advice. I think the harder problem is getting buy-in from everyone you work with to do this. Often times I take this approach and have to really try to sell it to people reviewing my code because they've bought into this idea of "DRY ever, no matter what". DRY yourself is useful when 1. You're repeating yourself more than 2 or 3 times and 2. The inputs/outputs and intention of the code are very, very clear. If that's not case, I'm ok with a little copy/paste.
