Great, I've got the "older" part nailed (turn 40 this year), but the other bit... um... yeah. I think my ego is about the size of the Death Star, so that might be a problem. :-(
Still, it is encouraging to see any research that dispels that idea that you have to be a 20-something to succeed as an entrepreneur.
Well, you can't get younger but you can always work on taming your ego :)
I'm 37 and have had moderate success as an entrepreneur. I would consider myself competitive but not really egotistical. I just try to hire/work with people who are smarter/better than me so I can always be learning.
Eh, I may be overstating things a little bit. I definitely have a substantial ego, but I don't think it's too the point that it's damaging to me. I'm definitely competitive, but I also value being humble. Certainly I acknowledge that there are plenty of people around who are smarter than I am.
Maybe it's not even so much ego, as it is a crazy high sense of self-efficacy. I still buy into that "I can do anything, if I'm just willing to work hard enough" mindset.
