Traveling in the same boat as you do, not eligible to advice. Although I read in HN before that burnt out is a signal by the brain stating that we are working without any foreseeable reward.
yes, that's exactly what my fear is.
me: how do make it turn out a reward?
brain: finish the last 10%.
me: all right let's do it!
brain: no.
me: all right lets play counter strike or read yc
brain: again? fine.
