Good Golf Sportsmanship

You'll probably ignore this post, but to be honest it is extremely important whether you are a veteran or a new player. Remember golf is just a game. How you react to the games events says more about you than how you play. You'll gain respect if you keep composure at all times, whether things are going well or not. By showing good sportsmanship you can also make friends with your opponent (and possibly somebody to golf with in the future)

Be a Good Winner
When you lose a game, be it golf, basketball, or water polo, aren't you upset? Consider that your opponents likely feel the same way when they lose. Don't gloat or boast when you win, all it will do is make your opponent want to punch you in the face. Whenever I win, no matter what I'm playing, I always go over to my opponent and tell them good game and shake their hand. This shows that you aren't all about winning and also helps to console your opponent. Your opponent will likely tell you good game as well and shake your hand as well. If they don't then they're probably just a sore loser, which is what I'm covering next.

...And a Good Loser
Let's face it. You won't win every golf match you play. Since you will likely be losing quite a bit throughout your golfing career, you need to learn how to be a good loser. After you lose, walk over to your opponent and tell him good game. Don't say anything else. Don't tell them about how you were "off your game" today or how they got lucky and beat you. Saying something like this just makes you look like a jerk. Depending on the stakes of the game they may be very excited. If they are so excited that they ignore you, just leave them alone and walk away. Be the bigger man. Show that you have class. Even though you may not be the better golfer on that particular day, at least you have better character.

Having good sportsmanship is extremely important. Treat others well and they will treat you well in return. Always remember the golden rule and make sure you follow it. By doing this, you will find that you will have better golfing experiences, as will those you golf with.
