Am I too old to start?

Im a 31 year old male , I have a wife , kid and one on the way. I have some art education from college and have worked as a graphic designer in the past. I work a full time remote job that I need to support my family but it is flexible. Should I give being an apprentice a shot ? It's seems risky but if I grind hard enough the reward could be great, I'd be looking for shops in the grater orange county area in CA so there's lots of great shops. Any advice would be appreciated , I love art and tattooing but taking the risk seems so scary. I guess I'm asking is this a bad idea ?
