So I know Yoda is a Jedi Master and all that, but he's got something wrong. One of his most favourite claims -- "Do, or do not. There is no 'try,'" -- has a big hole in it. He's suggesting that if you make enough of an effort to achieve a goal, you should be able to reach that goal. And that if you fail, your effort or conviction was lacking. That certainly hasn't been my reality.
