When you are on the green you should putt in three phases:
1. Plan
2. Prepare with a consistent pre-shot routine
3. Putt positively, letting it happen
Work on your fundamentals whenever you can ( The Frog Stick is a great tool to help you) and remember the three P’s!

I would also add Pleading and Prayer, though neither seem to influence my putting. =)
