I end up playing a lot of solo rounds. The people I played with in the past have moved away, work opposite shifts of me, or health keeps them from playing.
So when I can play with others I do try to win, but solo is great for trying different shots and not slowing the game up. A hole you normally toss a safe up the gut shot? Well, toss that shot, but try thay big hyzer over the top. Don't feel comfortable going for that 60 foot putt? Try that putt three times.
My suggestion on solo rounds are:
bring 3 putters. Throw them at every hole. Too many people try to get better by driving farther. The people that are the best are the ones that are automatic in the circle.
Get some behind the neck headphones. I've never had an issue with mine catching or incumbering my shots ever. And your music choices won't bother other players.
Try new shots. The only way to get better is to expand your repitoire.
Most important, and the one I have the biggest problem with, slow down. When you play with others you never drive, walk straight to your shot, throw an upshot, walk straight to it, putt, step over to the next tee, and repeat. Take a second in between shots and gather yourself.
