Make problems go away.

There are moments I want to quit.  Those are the moments I know I need to try harder. 

Of course you're tired.

Of course you need rest.

Of course you need to run faster.

You can rest when you get to the top of the mountain, until then...  Keep on trucking!

The amazing part is that after you stop concentrating how hard it is, it gets easy!  Before you now it the hard part is over.  Most of that is because you learn that all that hard work you thought was gonna be overwhelming...  Wasn't all that bad after all.

"If you focus on the problem the problem gets bigger.  If you focus on the solution, the problem goes away."
