Is there a more efficient way to writ a "Find" script?

I'm working on Android Unity Pro. My game has hundreds of "Find" scripts and I trying to optimize performance. Is there a better way to avoid writing a "Find" script? Below is a typical "Find' script in my game. This script is on a different game object. Remember, this is just an example of hundreds of similar "Find" scripts.If someone could teach me how to write it more efficiently I'd appreciate it. thanx

 function OnTriggerEnter( myTrigger : Collider){
       if(myTrigger.gameObject.name == "tum1-2"){
       var myTryagain : CameraControls = gameObject.Find("Main Camera").GetComponent(CameraControls);            
             myTryagain.enabled = false;            
         }
 }
