2. Stay Positive
A bad shot or two is inevitable and depending on your level of play, several bad shots are inevitable. If you can fight off those negative feelings, much like fighting the urge to lose your cool as mentioned above, you can stave off things from getting worse. It absolutely sounds much easier to do than it often is, but if you can learn to follow this pattern after a bad shot- Accept, breath, refocus, visualize a good shot, and think positive, then you are much, much more likely to hit a good shot after a bad one.
3. Stay Focused on One Shot at a Time
We all have those shots we remember at the end of a round that are the "What if'' scenarios...if only I hadn't missed those two tap ins, grabbing and hitting a wrong club, scuffing the green with our putter on a back-stroke, not backing off when that dog started barking on our backswing. In all these examples, a simple lack of focus can be to blame. Making sure you have a routine that you stick to is only part of this…being aware and focused during that process is what's most important...don't just do it to do it...make sure it has meaning.
4. Bit-Sized Golf
I've written about this before, and this is one of my all-time favorite strategies for playing good golf. Play your round, whether it's a quick 9 or a full 18, by breaking it up into 3 hole segments. Within those 3-hole segments, pick a total score to strive for and forget about the cumulative "par" for those holes. For example, if you are looking to shoot 90, then you need to score an average of 15 every 3 holes. So, let's say the first three holes are a Par 5, Par 4 and Par 3 and you start off double bogey 7, bogey 5 and a par 3, you may be 3 over on the card but you are level par for your 15 per every three hole target.
5. Enjoy the Game
My last bit of advice is this...Have Fun! If you love golf, then why get mad when things start to get bad? It's a game and it's meant to be enjoyed...no matter what...so enjoy and have fun!
