A How-on curving a bowling ball

I have always wanted to master bowling. watching many people doing the curve perfectly pushed me to learn how to do it. Here are simple instructions:

1- Start with the right distance which is at least 4 steps away from your release.

2- your eyes must be focused on the target pin.

3- First act like you want to throw it straight.

4-Release the ball at the bottom of your swing, pulling your thumb out before your fingers.
