Funny enough, the moment I stopped caring so much about time and optimizing it, the more productive I got.
Before I found that no matter how much time I had, I was always scrambling. This may be a bit too philosophical, but focusing on moment to moment and bringing attention to the problem at hand really helps.
I recommend reading Jacob Needleman's book about Time and the Soul.
"It is not, therefore, the rapidity of change as such that is the source of our problem of time. It is the metaphysical fact that the being of man is diminishing."
