Find an elite level bowler in your area and ask them who they have watch them when they struggle. Most everyone who is REALLY good will have a trusted advisor (or coach) from time to time.
Hooking the ball isn't the only answer, but learning to create some hook is helpful. Randy Petersen explains ball reaction very well when he says "when the ball encounters friction it will travel in the direction of it's rotation."
Memorize that!
If the ball isn't hooking it, 1) hasn't found adequate friction, or, 2) doesn't have proper rotation. Learn to watch your ball as it travels down the lane so you can see where it finds friction, etc.
Rant on: Learning to read ball reaction will be crucial when the normal house shot of "stand here and aim there" isn't working you'll know what to try next. Too many bowlers start blaiming the lanes for their bad scores because they can ALWAYS stand here, aim there and find the pocket. Rant off!
