I am starting up as well. I'm going after a little bit of a different market and with a different niche. But small businesses are small businesses, and they usually start from the same place. The odds are definitely stacked up against us. I've never believed a get rich quick scheme before, I wont believe it now. But i know this, if I work as hard for myself as I have for other people, I think I'll be ok. So coming from another jr., maintain a strong work ethic and plan for the negatives. Another thing I've learned from this site in the past year that I've been on - they have a friend's list, but they need an assholes list. There's a couple out there.
p.s. I'm a GMC man myself
