Over thinking a putt can have serious consequences for your game. Double guessing while putting is probably one of the worst things you can do while on the green. Many players fall
foul on the green because they take far too long to take their put, they over compensate & usually hit the ball too far. Many players take golf lessons to improve your putting but you can invest in a good golf video & this will be just as good if not batter.

The trick is to take your put in under 10 seconds after your practice put, by doing this you'll still have the feel for the shot & this can make all the difference to your game. What many players know but don't put into practice is that their first choice of shot was the correct one. How many time have you changed your put at the last second only to mess it up & then rant & rave to yourself that if only you took your first choice you'd have made the putt.

We've all been there, even the professional golf players have their bad days, they can make monumental mistakes also but they usually get them sorted out relatively quickly because they follow a code & although sometimes they can drift away from it, they will eventually return to it as they realise its the only way to play a good game.

When on the green, its better to keep things simple rather than over complicating matters, lets face it, putting is just rolling the ball so once you get this into your head it should calm you down a bit. You should always have a routine when on the green, most of the top players of the world will have their own routine & they will stick to it no matter what happens, by doing this they keep it consistent.

Keep it simple, before you take your stroke make sure you take a look from behind the ball about half way from your stroke & backwards also, by doing this you'll have a better feel for the green, you'll see the layout a lot better & be able to take better strokes. Always remember to keep the lower body stabilized when putting, when you keep your lower body stable you can swing the putter above the waste a lot easier. Remember, you don't have to follow what other players do, you should follow your own style so if you're a shoulder driven putter, then go for it or you may prefer a hands driven putter, its up to you.
