If, having studied PPRuNe, you are still not put off, I suggest you go for it.
Shoot high and try for a commission as aircrew. You have nothing to lose and much to gain, even if you never actually get to be an aircraft captain. Enjoy the ride. Do not be put off by talk of underfunding, too many demands with too little equipment, too much hot, sandy spots etc. As a junior officer you will not be exposed to the frustrations and pressures which come with more seniority and responsibility. Do not see it as a lifetime commitment. You can decide that much later.
When you are no longer enjoying it, leave. You will be very employable whatever level you reach and will have matured, learned a lot about people and life, and will almost certainly have made life-long friends.
