I feel like i might be getting to old to pursue this dream.. just turned 29
You're only too old in aviation if you don't maintain realistic aspirations. I routinely train new pilots at the airlines who are entering their second career in their 50's.
As everyone's dreams are different, it's hard to say whether you are "too old." If your dream is to do float flying for the rest of your career then no, you're not too old. If, however, your dream is to be #1 on the seniority list at a major international airline and also want to have 3 to 5 years on the top of the pay scale then yes, that ship has likely sailed and you're not going to realize your dreams.
