How to stop wasting time (and get more stuff done!)

The general consensus seems to hint that in his lifetime, the average person spends eight hours a day sleeping which translates to one-third of his life. I reckon that’s not too dis-similar from reality and thus constitutes a fairly accurate; if rather startling piece of information. Startling- because in light of this, a 90 year old has in fact lived for 60 years; with 20 years having been spent assuaging the daily exertions in sleep.
