When I was about your level, I asked my teacher what was wrong with my playing. He said, "you like gote too much."
The marked stones in this position at move 42 were all played in gote. So they must be valuable, right? And yet, what are they doing now? Take a long look those red circles and wonder for a bit if maybe that's where 3 of your 4 handicap stones went.

Okay, now look at the following position. I have removed the three wasted stones. Please, indulge yourself. You may now imagine adding 3 black stones to the board before you play

. Or you can move

if you like. How would that feel? Pretty good, I bet.

I remember reading a GTL review by Reid Augustin, AGA 5d in which he said something like "you must cultivate the feeling that it hurts to take territory in gote." So when you have to take a gote move, try to make it valuable, and even then at least wince a little bit while doing it...

Edit: one note on the timings. Although you were averaging about 10 seconds per move on this game, I think that's a pretty good pace given the 10 minute basic time limit. On these gote moves in question you were still in main time. Next time, you could pause a little and consider whether you really need to play them that way. It's better to be slow on the clock than slow on the board.
