thoughts on what I should do with my time

I can vividly remember reading Rick Warren when I was in college and him saying a phrase that stuck with me. He said something like "God gives you enough time to get everything done He wants you to do." Therefore, if there are things you know God wants you to do that you don't have time to do... you must be doing something else that's not necessary.

That impacted me so much that it has stuck in my head all the time ever since I read it.

I struggle with it too. Like this week for example I have so much on my plate that there is no way I can get it all done. I am consistently (for the past few months) empowering others and getting tons of stuff off my plate. BUT I still can't get it all done.

I feel like I am a pretty good time manager. I don't waste very much of it... if any.
So, I am trying to figure out what I'm doing that is not something God wants me to do? because (if Rick's statement is true) I should have enough time to do everything God wants me to do... and I don't think that's the case right now.

anyone else have this problem?
any thoughts on Rick's quote?
