That's exactly the mindset you need. Sure you're not the biggest guy, but does adding on 10 pounds of muscle really get you that much further. If Rey was an inch taller, would he be any better? If Masters had lost 10 pounds of muscle, would he still not be a great physical specimen? (No, I'm not gay). You can get into wrestling in so many ways, such as doing the technical aspects (Tazz was short, but he was great at suplexes), get some high flying action (how many cruiserweights are built), get great mic skills (Davairi...or something like that kind of spelling, didn't start out as a wrestler, he used his mic skills to get himself the attention).
