I don't live in the US so was tempted to be snarky about abroad being a big place etc. but I think it's better to put a more constructive reply with some context. On a visit to Kilmainham Jail I had a chance to read some of the letters written by the young men who were about to be shot by the British for their part in the rebellion. The thing that struck me, apart from their bravery was the fact that they had a genuine cause to believe in. And that I suppose is my point, if you don't have some Nobel cause then what drives you on? If the world doesn't provide some ready made cause then your motivation has to be intrinsic, the only problem is that depending on what your goals are (money, fame, being a better dad etc.) you can end up feeling a little grubby about your choices especially if you don't succeed.
