You can get incredible motivation from disappointment and go on to do great things. I have personally seen this unwritten rule Work in my life a lot. There were times when I really wanted to achieve something and situations and circumstances thwarted my efforts. All that did was to motivate me.

You have to learn to feed off negative energy and do something with it. I used that depressing situation and turned it around into something of incredible value. It shocked everyone I know and it even shocked me. I had no idea that I would be able to achieve so much in such a short space of time.

So my motivational last words to anyone facing incredibly painful times, is to go through them and conquer them. Do not, under any circumstance, submit to failure. It is not over until you die and even then the thing is questionable. Get up and work hard for what you want.
