No limits

I was never any good at cross word puzzles, I need real world consequences to hold my attention.
We are all capable of so much more than we think we are - we rarely test our limits.
If you are challenged and you don't have choice, how far will you go to get better?
I found out the hard way.
Having run a few marathons I knew I could meet a physical challenge, but we are never ready when life gives us our biggest test, whatever it is.
Sometimes it's up to us to create a solution that doesn't appear to exist. The perfect time to push beyond known limits is in a crisis.
Pull out all the stops.
Think of Scottie on Star Trek, "I'm givin' 'er all she's got Cap'n - she cannot take any more."
The Enterprise never blew up. They worked through it piece by piece.

Or how about the first sentence in Andy Weir's novel "The Martin "?  "My considered opinion is that I'm fucked."

There's motivation for you.

There may not be an obvious answer to a problem, but creativity and perseverance can open doors that may not be obvious.
Sit with how the problem feels, marinate in it. Become familiar with what it is about the problem you don't want. Be specific.
Embrace the challenge and eliminate the fear around the challenge.
Suspend your beliefs and allow the possibilities room to exist.
Take an easy first step to build on success.
Seek people with similar goals for support. 
Brainstorm.
Build a framework of what the solution looks like using simplicity as a guide, then check in with yourself regularly.
You started at step A, where are you now?

Oh, you thought you are done?
