Everything you have done until now has been to get this moment right.
Don't blow it!
The important thing is it to keep it smooth.
The worst mistake you can make in golf is to try and follow where the ball has gone too early in the swing as it is likely to mean you move during impact.
Once you have mastered keeping still, you should focus on three things;
If you slow your club head just a millisecond before impact you will not hit the ball anything like 100pc.
Rolling your right forearm will ensure you whip your wrists through the ball.
Concentrate on maintaining your hands ahead or level with the ball until it has gone.
Opening your shoulders will force you to open your stance to make way for the club to come through with maximum force.
