One tip I heard was instead of saving your time, you should spend your time. Maybe it was in a TED talk. There is a class on coursera for time management: https://www.coursera.org/learn/work-smarter-not-harder
I've also heard to spend a little time each day on each thing you have to do, not just your priorities. If you postpone everything until after your priorities are finished, maybe you'll never finish anything (that was my problem because my priorities are perpetual time suckers). When I was in college, working part time, taking care of household for aging mother, and dating, I scheduled my time without mercy. People like to hear the word 'priority' but that is all talk - IRL, everything has got to get taken care of both big and small.
Where does your current time management not work for you? Are you forgetful, or do you take too long or estimate poorly, or procrastinate?
