...and so if you read the above, you can gather some very good advice:

1) Stay healthy, and stay happy for the long term. It's not a sprint, but a marathon.
2) You certainly can be ambitious: create (and take) any opportunity to get a seniority number at an airline that you value. Paddle hard early, then ride the first hiring wave in the set.
3) Once you get to where you were going, stay there. Don't make a bunch of lateral moves trying to second-guess the future of any given company.
4) Don't worry about things you can't control. Like your age.


Good luck!
