Well..thats a tough question. 35.. thats pretty old to start out if you want to get to an airline. Maybe somewhere smaller ora regional ??
I started training when I was 28 and was told I had missed the boat as far as the airlines were concerned at that age !!
But it wasn't my thing so no loss anyway. It actually took about 6 years from first lesson to first job but a lot of that time ws spent earning the money to spend on training. I guess if you are fairly flush you could cut that time down a fair bit.
The bottom line is you either want to fly or you don't. Thats the only question. And you're the one with the answer.
If you are going to go for it my advise is to get as much advice on the way to do it as possible and then get more advice. The only thing worse than a false start is a second one
Good luck
