It made me realize that when we view "great feats" achieved by another musician, the situation might look very different from that musician's point of view. I discovered that when you're that one crazy musician, you really don't feel like it.
You just feel like you're the last one left to get the job done.
It doesn't feel great. In fact, it's a hell of a lot of pressure, and there's no warm rush of victorious feelings while you're doing your crazy job. You also end up thinking, "Man, if only [insert name of someone else you know who could do this too but just happens to not be around to do it] was here, then we'd all be better off. It kinda sucks that they just have me." You think that a lot.
So when it comes down to it, you probably have already done wonderous feats of bravery and don't even know it. You just had a drive and a reason strong enough to persuade you to do it, even though you felt like it was impossible.
These feats, when done right, are never done to just pump up one's ego. It's done for the sake of others. :)
