NO but it sure doesn't hurt. My income is somewhere between middle class and poverty but I still love running field trials, you might say I'm living a field trial lifestyle on a hunt test budget.
I have definitely have had to make some compromises and sacrifices like telling my kids that I'm spending their inheritance money, thank God they are ok with that. I gave my golf clubs to my son because I don't have the time or money to do both.
I had to promise my daughters that I would never ask them to throw me a dead duck but my grandkids are another story. I have never paid a pro trainer but on the other hand my goals and accomplishments are probably not as big as people that do.
Being retired definitely gives me more the time to put into this very addictive sport and I've be blessed with hooking up with great amateur trainers along with access to great training grounds. Instead of spending my money on fancy clothes, expensive restaurants, and exotic places, it goes for Mike Lardy videos, Gonia whistles, white coats, Motel 6's and pheasant and duck flyers.
The last trial I ran this year was a 31 dog amateur with only 5 dogs finishing the trial, out of those 5 dogs two of them were mine. I was grinning from ear to ear and dancing around like a crazy person, you would of thought I just won a National.
No doubt about it I'm field trialer for life.
