I think you have thought it out well, and most people on here would probably agree. Don't quit your job if your making good money to start flight training. My biggest suggestion would be to have enough funds available to finish an entire rating at a time. When you have to take long breaks during training (which is common with students who do not have the funding available, and pay as they go), you end up spending a lot more money to re learn everything you had already learned. Also avoid getting loans to fund training at ALL COSTS. They are almost impossible to pay back for the first few years. Start out with your private, see how you like it. If you enjoy flying, then add additional ratings when you can. After you get your commercial, if you are still interested in a pilot career, get your CFI and instruct on the side to build hours, but keep your current job if you can, unless you are very financially stable and have no debt. It is very difficult to support yourself on a CFIs salary and for the first few years at a regional. It will take longer to build the time, but at least you will be able to eat
