My personal dare

So, I have recently realized that I spend way too much time doing things that don't matter and not enough time on things that do matter. Obviously not being able to go "cold-turkey" on these time-wasters I have created a dare, that I have already shared with a friend. What is this dare??? Well, I will explain using an example. I spend way too much time on Facebook. Let's use an hour of my time on Facebook for this example.
~ Ok, the hour that I usually spend on Facebook is now split into sections of other things.
~ 25% of the time, 15 minutes, will be spent with God.
~ another 25%, another 15 minutes, will be spent on homework.
~ the other 50%, 30 minutes, will be spent on Facebook.
My hope is that slowly the time with God and homework time will grow greater while the time on Facebook decreases. I realize that Facebook won't ever be completely out of my life, but it will be for the best if I start decreasing the time now, for when it really matters and I have more important things to tend to...
