Ratios -
It's been my experience that the ratio of people who talk about touring vs. the people who actually do it is about 20 to 1. I can't tell you how many friends, co-workers, and grad school colleagues have insisted that they want to tour in January only to find some other pressing matter come May. If you don't do it now, I suspect you will be 75 before you realize that you never have gone on a tour. Which side of the ratio do you want to be on? It's 99% mental.
