It is possible that you may fail but that is in no way a reason to quit or to avoid anything. In reality, it is more of a reason to keep focused and make the effort.
When there is a real possibility of failure in what you are doing is really the only time that there is more of a possibility of success. Something will definitely happen and it is not an accomplishment without the difficulty.
The stuff of success is the difficulties and the challenges and getting through them to make your success happen. The larger the trials you face the more prized your success can be.
So quit hoping for something easier in your life and seek the extreme value in the challenge that is in front of you. Each of us has the ability to figure anything out and get something done so get busy and do it.
Every challenge and every difficult situation is an opportunity to make a very positive difference. Grasp that opportunity every time it comes your way and you will create value in your own world.
Relish in every challenge and difficulty and find your joy in your ability to make your way through them all. With every curve you are creating more elements for success.
