I did that at 27, and it took me about 5 years to get into the sphere of where I wanted to be. Best thing I ever did. Even today I was talking about how sad it would be to hit retirement and to never have truly done what I wanted in my life. Now I have none of those regrets.

However, it was a hard road, and I travelled it when conditions for developers were much better. Along the way, I made some missteps, and followed the wrong path a few times out of sheer lack of industry experience. I had to make the kinds of mistakes you usually make at 22, but at that age everyone you know is also going through the same experience so it feels like everyone is going through it together. It’s a lonelier road when everyone you know is hitting senior/executive/management/ownership level and you’re back trying to figure out how to find your footing on the first rungs of the ladder. I didn’t love the work I used to do, but I was becoming respected when I left it and would have done quite well, so for _years_ I had the constant nagging doubt that I had made the wrong choice and that maybe the grass wasn’t greener after all.

That’s my experience. If you wanted advice (which you can ignore a la “wear sunscreen”), I’d tell you to keep your current job while you work on your passion projects. Try to get involved with dev meetups. You want to see if you want to become one of those people, and you want to see if the stuff you’re doing gets any kind of traction. Meetups will help you figure out how to sound like a developer, which can be more important than it should be. You will have to fit in with developers to get past interviews if you’re looking for a job.

Whatever you decide to do, best of luck. I hope it all works out for you!
