I've been trying to kid myself with similar rosy-tinted views of my financial future for the 20 years since I was your age kid. Life has this rather annoying habit of throwing spanners in the works when you least expect it. Whilst I admire your clarity of vision and determination, be very careful about expecting things to just keep running along the way they are now.
As has been said already, you are tremendously fortunate to find yourself in a very strong financial position at such a young age, but you need to realise that whilst this may be normal for you (or even your friends), you are going to meet many, many people who have come from a vastly different financial background. For those guys, training without a loan is not an option at all.
There are FO's out there earning less than you in their first full-time flying job, which in itself is a substantial improvement on their previous earnings, who are almost 20 years your senior, with families and major finacial commitments. Just bear that in mind when you eventually start your career, and I'm sure you'll get off to a good start.
Other than that, I'm sure we all wish you luck.
