If you are the owner of a business that generates more than 1MM in sales, I'd highly recommend you consider joining EO (Entrepreneurs Organization). I joined EO when I was 28 -- at the time the organization was called YEO. I've been a member for 12 years now and have made some of my best friends and business acquaintances in the group. In addition, I've learned a lot from the people I've met. The organization is now international and has thousands of members. Check it out in your city -- it's definitely worth the cost (and the cost is not insignificant).
