One thing that works for me is if I don't have time to warm up. I just try to ease into it. The first hole at my home course is a par 5 off a bluff over a lake. If you aren't on the money it's easy to slice into big trouble. I just make a good easy swing. My main goal is to be in the fairway. Plus being a par 5 I have two more shots to get me there. I shoot to be on in no more than 4 and 2 putt. Then increse my prower over the next few holes. But as the guy said before If you can just try to reach the par 4's in 3 and the 5's in 4 and two putt you will be playing bogey golf which on most courses is a 90. Throw in a par and you are in the 80's
