A question that I have started asking myself when I have trouble starting to work, or finding particular motivation to do something specific, is:

"What will I most regret not having done now?"

This is a replacement to my usual question of "What should I really be doing right now?" I find this version helpful, since I am not very self-disciplined and usually want to surf the web or smth vaguely fun, so work seems like a chore. This question makes me feel like work is the opportunity for future happiness, which makes it seem attractive. It helps me view work from the perspective of it having been completed, which is the best kind of work.

Okay, just a thought.
