You've got to be good to each other. . . it really comes back to respect. I was raised in a very Catholic, Italian family and it was all about respect. Don't talk badly about [your partner] the second they walk out the door; really preserve your relationship and be good to each other. Treat it like gold.
When you lip out several putts in a row, you should never think that means that you're putting well. When you're putting well, the only question is what part of the hole it's going to fall in, not if it's going in.
