I took my first flying lesson at 35, and (due to rapid expansion rather than any skill on my part I might add) I'm on the cusp of starting my first commercial job at the tender age of 39. I used the modular route and spent over a year instructing.
I too was worried about my age, but if the market is there, age shouldn't be too much of a factor for you. I relieved to get in before the big four-oh though.
The hardest bit is deciding to do it. Once you do, just go all out for it. It requires a lot of hard work, but if I can get there - a young 'un like you should be okay!
Good luck with whatever you do!
