Joe,
Is it just a myth, or is it true that if you act confident when you putt, you will make more putts?
Ashley

Hello Ashley,
It is true, because those who feel confident are committed to the read and to the execution of the stroke. Those who are not confident of the read are not likely to commit themselves to make a confident stroke. Instead they make a tentative stroke and look up too soon. The lesson here is that even when you are not sure of the read, you must commit to your best guess and make a confident stroke. A tentative stroke has very little chance of success.
