People here working your own business or side hustle:

1) How long have you been doing it?

2) What kind of tech stack do you use in your product(s)?

3) Are you happy with your business endeavor or has the grass become greener elsewhere?

4) What is the most important thing you have learned from it that you wish you knew when you began?

@M1sf3t that's cool, I wasn't expecting something outside of the software world. What kind of a shop are you running?

I'll add my own answers to this.

1) 7+ years

2) C# with a heavy micro-service architecture. Primarily SQL for data persistence. RabbitMQ for event messaging. AngularJS for the various (legacy) app UIs, transitioning to a much more modern React.

3) Yes, I'm very happy with it all but of course it's not without it's stressors. I'm glad though I left the regular job life.

4) I've thought about this question a lot, and I can say for certain that the answer tends to change for me from day to day, but the most consistent feeling I have is that it takes all of you. It will take far more of you than you realize. If the desire is for it to take off in a big way, there can be no holding back, even 7+ years in.
