Its very important to try out things and when the obstacles seem unsurmountable ,it is even more important to create situations that make you go for it. This is superbly narrated in the form of a story by Seth Levine:.

Two friends were walking together through some fields when they came to a high wall. The wall stretched as far as they could see in both directions. As they were talking about what to do in this impassable situation one of the men takes off his favorite felt hat and throws it over the wall. The other looks at him and says “why did you do that – that was your favorite hat,” to which his friend responds “now we’re going to have to find a way over that wall.”
