Don't worry about not having big arms and what not. I certainly don't have big arms at all, but last week snatched by bodyweight and ohs it, 190. And then worked up to a 335 behind the neck jerk. I find that the more I think about developing my muscles, the less attention goes to increasing my OL. Just decide what you want to accomplish and go at it.
You could be as strong and big as a bull and someone may think, "he probably can't run very far"...or if you are very slim think, "that guy is too skinny." You can't make everyone happy and you certainly can't train every athletic quality (strong, ripped, explosive, high aerobic endurance, huge,etc..)at the same time and expect to be great.
