I started at the age of 39. Got my PPL 1 year ago. Got my instrument. About 2 months away from my Commercial. Lined up a 2 day course to do a Multi add-on after that. Still chewing on whether to add the single engine seaplane. CFI work is too full at the moment but I'll eventually grab the CFI as well.

If you love flying you'll never regret going for it.

I won't pull the punch. It's hard work, it'll eat up all your spare time. If you don't have a supportive spouse you might be signing up for a divorce. It's extremely expensive, even going the part 61 route. If you get started now and manage to land a job with your wet commercial (unlikely) you should be ready to grab a slot at a regional when demand comes back.

Good luck. PM me if you want advice or have specific questions.
