I was self-employed for more than a decade and I made $300k - 400k for years. I'm not at all worried about the corporate life. If I don't like it, I'll go do my own thing again, no problem. What I won't do is work for a third of the income and convince myself that I'm one of the cool kids because there's a ping-pong table in my office and my "CEO" made some 30 under 30 list.
