Work three times harder than you did in college and get your platform choice then wings. FW is easier but I and many others made it through the helo route. Fly as much as you can and do the ground stuff the best you can. Performance and flight time/quals matter. Keep an open mind to a career but always have an exit plan. Then a plan B and a plan C.
Airlines are a great job but not sure I would have been happy at it in my 30s. An airline job plus a reserve job is balancing act of keeping momma, the squadron, and your airline equally ****ed at you. Flying airplanes without a ground job rocks but unable to ever change things doesn't. YMMV.
All you can do is control your now. And enjoy the ride.
