You all might be familiar with this problem; you have to finish a paper within one day - yay for not starting on time - but you still have to get some groceries and a friend invited you over for some drinks that night. So much to do in so little time. If I had a magic wand, I would make sure a day had more than 24 hours.
A while ago, I read about this technique at Misslipgloss called the Pomodoro Technique which is great for getting stuff done within a short period of time. One Pomodoro equals 25 minutes of working and after those 25 minutes you have to take a short break of 5 minutes. When you've finished 4 sets of 25 minutes you can take a break as long as you need. If you want to learn more about this technique you can visit their website.
Unfortunately, this doesn't make a day last longer than 24 hours but I am sure you will find this technique helpfull for making those 24 hours more efficient.
