There's a course I play when I am in FT. Worth (Rockwood) that is really tough for me to break 90 on. My poor putting, (for what ever reason) is usually the culprit. A bit frustrating to say the least, but I just keep playing that course multiple times on every visit. Other courses in the area are no problem for me to play my normal game. I think I have quit this game probably a couple of 100 times in the past 45 years. I think the longest period of time I was actually done with golf was probably and hour or so.
