I’m far from a success coach, but I often wonder how some people plateau and other’s continue to excel (in anything). I think motivation is a key factor. What motivated you to start PE to begin with and have those needs been satisfied? If they have been satisifed, have your tried reducing your routine to a point where you are doing the minimum amount of maintenance and pick up another hobby. If they haven’t, were your goals set too high or what will motivate you to the next level.
Sounds like you are a little burned out (or too few results for too much effort).. I get that way with golf on occasion. Practice begins to feel like work and the act of playing golf brings only frustration, but yet I can’t stop playing. I developed a routine that would allow me to shoot in the high 70’s consistantly, the biggest problem was that it required 10 hours per week of practice, which negatively impacted other areas of my life.
I find PEing to be a difficult sport. You aren’t competing against other players directly, no one knows how often you practice, it just comes naturally to some people, etc.
