You should follow your dreams..There will always be people that think, once you take the road less travelled, that you are mad. Ignore them.
If personal training/martial fitness is your passion, follow it! It never hurt Steven Seagal, Chuck Norris, Bruce Lee or Jackie Chan. Make a business out of it. You'll make a far better success out of something you are passionate about than something you aren't.
A guy started the website bodybuilding.com and began selling supplements for people interested in bodybuilding. Do you know how much money the site grossed 2 years ago? $48m in one year and the owner says that he still sees room for additional growth.
Another guy who is a personal trainer has a business in NY preparing white collar convicted criminals for jail..teaches them the lingo, how to defend themselves, brings in the policemen to give them short courses in what to expect etc. You know how much he charges? $20,000 per person for 100 hours. He grossed $600,000 last year alone from 30 clients and he too sees room for growth
Find your niche and then go for it.
