Whatever has happened "to you", life still goes on....so wipe them tears and get back to it. 

There will be seasons where your energy will wane, and what was once easy becomes difficult. Accept where you are, just commit to NEVER quitting. It's ok, just as long as you don't quit.

Regardless of how well you're doing, refuse to lose your edge. Do not listen to the people who tell you to "reward" yourself with rest and ease. Keep applying that pressure, that's what will get you to the next level.
