I normally make a habit of gging all the time but I started to slip in frustration after cannon rushes/4-gates/ZvZ all-ins, etc. (I don't lose much in ZvT so when I do I always type gg - no complaints with that matchup when you're winning 80%)
Then yesterday and today I played two games, one loss and one win that just made me step back and enjoy the games for what they are instead of stressing about promotion. One was a grueling 45 minute affair where a terran got the best of me, the second was a 31 minute game I thought I was going to lose for sure but managed to pull out by the skin of my teeth. I'm 100% positive a month ago I would have just lost the second game after I had my 4th and 5th destroyed but somehow I won.
If you think you'll enjoy mid-to low diamond level play you might like these games:
(Z)p4NDemik vs (T)Chris on Backwater Gulch
(Z)p4NDemik vs (P)redalert on Metalopolis
Basically I just want to say to all the guys grinding through ladder, enjoy your games and don't take the losses too hard because you'll have games like this where you can really feel the improvement, which is loads more satisfying than any promotion the ladder systematically gives you.
