Edan - I'm 25, never had any training just like a couple of months of BJJ and kickboxing, I will be 26 in october, is it too late for me to start right now going pro or should I just think about it as a hobby?
Never too late ask Randy Couture 
Just...Start...TRAINING!!! Make small goals and just work hard.
If I recall correctly Frank Shamrock was 26 when he started training and he became a star in Pancrase, UFC champion, a pioneer of the sport and the symbol of the evolution of MMA from gimmick to a modern sport with world class athletes.
If you are going to be world champion one must admit you have a lot of catching up to do, but if you train hard and enjoy yourself you may end up noticing that you don't really suck at it. Go from there. I am 32 and only had a handful of training sessions so far and already signed up for a grappling competition in 3 weeks. =) If you don't have to be world champion, just push on and bloody enjoy yourself.
By the way, when did Severn shift from wrestling to MMA? At 36 or something?
If I recall correctly UFC fighter Jorge Rivera trained martial arts for the first time when he was 25.

I dismissed the idea of going into MMA, and have been taking TKD since last November, and am very happy with it. 
Dooo ittt, definitely won't regret it.
