A lot of whatever success I may have had in recent years has come from getting past those internal roadblocks. Not to discredit everyone who's helped me along the way, but before anyone could help me, I had to help myself by returning to that notion that I can do anything. That there are no barriers before me.
I've collected a series of about twenty 2-ish minute videos that I use as inspiration. These are snippets of biographies of people who should, by any conventional reasoning, not be doing what they're doing. Whether they were born with cerebal palsy, or they lost an arm in an auto accident, or they happened to be born in one of the poorest regions on the planet, these people not only cope with their "limitations" but strive and succeed in spite of them.
They range in professions and notoriety. From kids who are still in school to stand-up comedians to Olympic athletes. These people let nothing stop them. Not a physical disability, not a mental disability, not a health problem that grew worse over time, not a single life event that left them devastated. They all achieved greatness not because it was something they were given, but because it was something they sought for themselves.
