Another example is when I used to lift, I was obsessed with it, and it was the only thing I thought about for 1.5 years, but even towards the end when I knew everything needed, I just kept switching programs knowing it was hindering my progress.
There are other 10+ things Iβm currently trying to improve like my posture, flexibility, music, social skills, research on self improvement, study, declutter my room/car but most of the times I forget what to do.
