Time...Management?

Time management. Something we hear about throughout our lives, but how often do we actually manage our time?

First of what is time management? To me it means that you get what you need to done, in the time given, without burning yourself out. 

I am probably one of the worst people at time management. I go home, get on facebook and Pintrest and waste the day away on the computer. Occasionally, I will practice the piano or go outside, but it has gotten rare.
