​Quitting my corporate job of 15 years

I am quitting a $150k per year job to go out on my own and help my wife run our small business. 2 years ago this July we purchased a small industrial/commercial pump distributorship in South East Pennsylvania. I’ll have 15 years in with my current employer and I gave them plenty of notice so I can train my replacement.

The business has almost doubled since we took it over and I have found myself traveling more frequently to meet with customers. My corporate job has a very flexible work policy so for the past year I could flex my hours around appointments to make it work. Although I was still working my 40, plus hours for the business when I had them. Over the last few months those hours just keep piling on until late at night. It’s exhausting, but I also love it.

Anyway, just wondering if anyone else spend a lot of time in the corporate world before heading out on their own? What was your biggest challenge? Do you regret it?
