It's definitely worth a try, but as others said, don't expect it to be easy to get in as the requirements are very tough. My other half wanted to get in as an ATC controller but didn't manage.
I personally had the same feeling after working in IT in London for a few years. At 27 I decided to become a pilot and I just went for it. It took me a few years and it certainly wasn't easy, but here I am now, doing air ambulance work on a light twin engine aircraft in the UK, which is very badly paid but very rewarding and unique. Sometimes you just have to go for it, just make sure you don't lay all your eggs in one basket. I still have a backup career to fall back on should it all go **** up.
