Most people practice more when they're playing badly as opposed to when they're striking the
ball well. When you're playing badly, it's time to take a lesson - not practice a bad swing.
When you're playing good and striking the ball well is when you want to practice more so you
can learn to repeat that good swing. To be good at your practice you must think on every shot
and develop a good routine. You're better off making 10 good thoughtful swings then hitting
50 balls rapid fire with little thought. Also, when practicing don't hit too many balls without a break
because fatigue will set in and swing will break down.
