1.Join the Navy or Airforce (make sure to sign up for the GI bill) The pay deduction really hurts the first 12 months, but it's worth the sacrifice.
2.Get your 4 year degree while you are in. (they pay 75%)
3. Leave after 4 years. (get a full time civilian job and start saving cash!!)
4. Get your private pilot rating at a local FBO. (cheapest way)
5. Go to a VA approved 141 school and get your Inst. , Comm. ,CFI, CFII, and Multi. The GI Bill will pay 60% of your training and you can get an education loan for the remaining balance)
6. Stay at your good paying job and instruct part time until you payoff your loan or you can use plan B and get married and put the spouse to work to help pay your education loan off) also, don't have kids if you chose this option.
7. Start instructing full time, and find a way to build multi time. (it's hard to get, so don't get discourged!)
8. Apply at your favorite regional!
By applying these steps, you can be in your dream job in 6 years with no debt and have an degree to fall back on. So if your started at 18 (right of of high school) you could be in the right seat by 24 with a good 41 years of flying still left.
