So today is the day of the week I feel stupid for not being rich (yet) thanks to my skills in coding. Thank you, @pyeu ;-)
Most small businesses fail. Some do well for a short time, then fail. There are a lot of completely miserable people out there. Your #1 job is to NOT be completely miserable. If you can succeed with a small business (or even a large one) that's great! But like I said in my other post, there's a ton of bs out there.
