I watched a movie on Netflix sometime ago, Into The Wild. This is based on a true story. It was one of those movies that stayed with me, not only because it was a true story and the main character died, but because of the inspiration that came from it. If you haven't seen it check it out, or Google his name.......Chris McCandles. It is also a book.
Of course, without going to the extreme of what he did, I believe that you should not remain stagnate in this life. There is so much to do, learn, see. You can explore in your own neighborhood and find something new or learn something new. You don't have to have money to do this. The library is a vast resource of information.
You cannot grow if you don't expand your mind and fear, it will paralyze you. When learning something makes you uncomfortable, do it. Push. Because in the end, once you do what you think you can't do, it is an amazing feeling to experience in itself.
