This is why I left "Corporate America" many many moons ago. I am not a company guy that likes to socialize with co-workers. I did it because I had to as an employee. Now? I don't have to do anything I don't want to do. It's my company, and I choose not to drink (because I do not drink). I choose not to socialize in business (because I do not enjoy talking shop until 4 AM - especially with someone I have been working with since 8 AM).
In the corporate world, I do not know if you really have a choice. I did it for 20 years. That was long enough.
So yes, I agree with you. These days, I travel, and when my work is done, I go back to my room and do whatever the heck I want. Read my Nook, order a movie, go to a club and work out, or MEET FRIENDS (not co-workers) for dinner. It's what I like to do, and it's one of the perks for running my own business.
I personally found that trade shows and long after-hours socializing and "networking" were a huge waste of my time and money. Drinking alcohol until the wee hours may be a fun game for 20 year olds, but not for me. Those days are LONG over. Maybe others disagree. To each their own, but it's not my idea of a rich and rewarding life.
And, it's sure as heck not my idea of how to be productive and successful in business. At least now that I am running the show.
