If you want to be recognized in orc society, you need to be strong or smart, you need to demonstrate how strong or smart, and you need to do it in a way that people care about. Punching a mountain in half is impressive, but Orcs probably wouldn't consider you important, just strong. You need to be strong and helpful. Same with smart, you can know everything there is to know, and nobody will care unless you apply it in a way that helps the orcs.
