Starting a second career late in life is a great thing. Most likely you have finally decided to pursue what you always wanted to do.
Just be careful. At least by now you have age on your side and the life experience that comes with it. Our industry is a weird one, and I constantly find myself having to explain certain aspects of it over and over again to friends and family.
Don't spend all your money on a program that will get you nowhere fast. I'm especially thinking of the ones that makes a lot of promises up front. And like somebody mentioned earlier don't pay to sit right seat. Yes you can probably get away with it, but it degrades all of us and our profession.
Take the time to research, it will be worth it!
Also you might think now that this a big world, but it amazing how small it really is. For better and worse.
And start networking now! That is really where most of your energy/resources is worth being spent.
