I agree with warren,if you tend to strike the cue ball with power,you will need to reduce the amount of spin you put on the ball,you can also treat the cue ball like the face of a clock for using spin,provided you are also using the cushions from it,you can also use spin to "turn" an object ball,but that's best left to the good players,which i'm not one of them,another small tip,when in practice,use the cue tip(a) as a guide to the object ball (c),by striking the cue ball(b)dead centre.if i am wrong,i'm sure other players will correct me.gl.
