I set up my own IT business about 10 years ago and it’s still going strong.
There are upsides and downsides of course. For example, in a 9-5, usually you finish and you don’t have to think about work until the next day, but I find I’m working quite a few hours at night each week to keep the work coming in.
I don’t have a boss, but I do need to think about funding my own pension, training, sick etc.
Good luck, if you want it enough you can make it work.
