Well, for productivity, I've got a notebook where I quantify everything useful I do (and then run the stats using a website), and I've been using the Pomodoro method. Some introspection: I realized that I don't ask myself enough questions about what I'm learning, so I give myself "points" for questions posed. Everything I want to do more of (problems, concepts learned, exercise, errands) nets me positive points; everything I want to do less of (eating out, daytime sleeping, websurfing) gets me negative points. I also have an internet blocker that's been working out well for me. I've been reflecting regularly on what I want and what I'm doing it all for.

For having a better relationship with the truth -- being less afraid to find out unpleasant truths, being more eager to find out the state of reality -- I haven't got it all figured out yet, but one thing that helps is being in contact with supportive friends. It gives a sense that no matter what I discover, I can be honest with myself and others, and still be emotionally "safe." The other thing I'm trying to remember is to be more detail oriented, to recall that small or seemingly dull details often aren't superfluous, but essential. (Mathematical example: realizing that functors really have to be functorial or the results will be awful -- demonstrating functoriality isn't just a busy-work exercise.)
