I find the atmosphere very gratifying. I think it's cool. I tend to do everything a few years after my peer group does, anyway. For instance, I just got married. At first, I felt a little paranoid about being in such a young industry, but I've gotten to like it.
Curiosity is key.
Social skills are key. Part of what I do is cold calls, a lot of times to people pretty high up in a company. I don't particularly like that part of my job. It can be very frustrating, but I've been able to hone that skill and achieve a better success rate. You also need to understand the economics of the industry.
