The last dejected effort often becomes the winning stroke. – W.J. Camero

What is one of biggest the keys to success?  Persistence!  When you feel like you have given every last effort to something, and you give it that little bit more, is when most breakthroughs occur.  Sometimes fear can get in your way.  Just give it just one more try and then one more until you get where you want to be.  You have already spent a lot of time and effort, don’t throw that away!  Fight for it, you have come this far, don’t quit!  Even if you can’t possibly see anything that could help, reach out and take one more try.  You never know what could happen.  Big, meaningful achievements don’t just happen when everything is going your way.  Keep trying.  Remember the toy cars from long ago that would keep running into the wall and make a small turn (correction) and keep going until it found the way out of the room?  Be that toy car!  Just keep going until you find a way!
