I remember when I first started and would go to my local ADI, electrical supply house or training, I was the young pup.
The only guys in my age range were the helpers and wire monkeys. 
Even meeting with clients was sometimes a struggle to relate with, as music taste and TV/Movie choices were vastly different.

As a business owner, I felt like I didn't belong, or was trying to get away with something.

Nowadays, with years creeping up, married, divorces and re-married (10 years each), kids and grand kids in the house, I don't feel out of place anymore. 
I miss the good ol days :-)
