Mark Twain once said:

''Twenty years from now you will be more disappointed by the things that you did'nt do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover. ''

Always keep this in the back of your head, like I do. Everytime you are afraid of falling, everytime you are afraid of takings risks, always remember this.
