I highlighted the incredible story of Scott Rigsby, IronMan extraordinaire in this Feb 2008 post on doing the unthinkable.
Tonight I was pleased to watch his new short movie.
(2017-03 update: it looks like ScottS7 original site has become a non-profit foundation for his amazing work. This extract on the IMDB gives a good idea of his IronMan Movie.
Honest to goodness, a better example of a true IronMan hero to marvel at would be hard to find, even in Hollywood.
His achievement is really inspiring and maybe will help you run through your own open door.
