Twenty years and counting and I don't regret a minute of it. I'll be one of those old guys that won't retire until they force me to. I love it so much; my wife says I get downright ornery if I don't get out flying on a regular basis.
Just don't let yourself get into a rut. If you don't like what you're doing, try a different aspect of the industry, it has a lot to offer. I used to love hanging my head out the door and slinging drills all over the hills, but the family-life/conditions made me move on. EMS was alot of fun, I liked the professionalism and excitement, and the schedule and homelife is much, much better, but I found the odd taste of actual IFR just wetted my appetite for more, so now I'm flogging heavies in the clag all day, yet home everynight, and making good coin to boot. If traveling is your thing, I doubt there are people that have seen more than guys touring offshore. It’s a great life, but you may have to work abit to make it fun. Life's too short to be miserable!
