For the last few months I have been trying to figure out how to be able to answer yes to this question. Unfortunately I have also been failing rather spectacularly at it, the junior programmers my boss hired and assigned me as something of a mentor for have shown very little improvement (sometimes even getting worse).
Unfortunately I was "gifted" with the ability to work with other peoples code, at least when I have some clue as to the intent. Now before you start saying "oh how nice for you", it wasn't said to brag, it was an excuse I keep telling myself for not being able to help them. I mean the only thing someone "gifted" with a talent would have to brag about would be something like "my <insert your deity> loves me more then you", which is just childish.
I'm sure part of it is that both of them are "at work only" programmers, so the likelihood of them doing anything listed on any of the being a better developer lists that had been going around a few months ago. As of late I have been finding myself acting more and more like a the Jeff Atwood suggests might been needed in coding discipline enforcer then a mentor and thats not doing anyone any good.
Anyways, if you have found an effective method for teaching others this talent feel free to share it. I'm getting tired of feeling like my collage statistics teacher.
