Without heart, you won't get far. you could be the best wrestler, have the most stamina, be the strongest, but if you don't want it, you won't get far. Of course you need all the other elements, but i honestly beleive that heart is the most important key in wrestling. I'd have to say technique and stamina is next. Strength is nice to have, very nice, but i personally am not strong...at all, so i have to rely on the other aspects if i want to win a match. I try to learn the moves we work in practice, and I try to get as good as I can with the moves that I know, a lot of times in the weight class I'm in, i'd say 90% of the people I wrestle against are stronger than me, so i have to rely on what i learn in practice and my stamina to win matches. I've been looked at many times and underestimated just because i have noodle-like arms, but i try hard and work what i know, and most of the time it gets it done.
