I don't know if I would call it burnout, but I go through a period of indifference every year, usually in August. I'll put the sticks away for a couple of weeks and get them back out after Labor Day, with new energy and interest.
I can relate. I have done the same thing many times. I think it is because, when on the range, I am simply focused on the process of the swing and the shot. When I get on the course I get all worked up about the possible results instead of just focusing on the process of the shot. You know it's in his head when tries to bump a 4 iron on a 25 yard shot that he has been making with a wedge his entire life.
Who still has a land line telephone?
A few years ago, we investigated who called us on our land line phone over a period of about 6 months. The only person who called us on that line was my brother and the rest was marketing calls. We dumped it immediately and haven't missed it for a minute.
