I'm realizing more and more these days the importance of managing my life. You might say "Yeah of course, I want to manage my life! duhh!"
BUT DO YOU MANAGE YOUR TIME?
1 hour of time = 1 hour of life
24 hours of time = a day of your life
168 hours of time = a week of your life
... You get the picture.
If you waste your time, even 15 minutes of your time... you have just wasted 15 minutes of your life.
I don't mean you always need to be doing something - I just mean you KNOW WHAT YOU'RE DOING and WHY YOU'RE DOING IT!
