You need to factor in the process of time building typically 2 years at minimum wage. So factor in 6-12 months of training +1.5-2 years of time building where you most likely are just breaking even. ( most of my friends were on food stamps/medicade as cfi’s) On top of that you’ll need to have the funds for training. Training at a school like Atp is about 80k +living expenses.

If that all sounds good you’ll have to consider how you deal with the stress of your career progression being on the line every time you take a Checkride. Some deal quite well some not so much.

Flying has great aspects but it’s certainly different than I expected it to be. A discovery flight is a great idea, I would also suggest going to an Ame or contacting aopa about the medical requirements.
