Good work.
Two additional techniques that are very powerful:
Journaling. This means keep track of your workouts and progress. What I recommend is also recording injuries, health issues, and obstacles. This is tremendously valuable in the long term. It also seems to strengthen habits. Sort of like the maintenance manual for your car. I also recommend using a physical wirebound journal, with a pen/pencil, rather than some type of electronic solution. My journal has sat in my car in 120 degree texas heat, had liquid splashed on it, been dropped .. no issues!
Visualization. Very powerful when mastered (I haven’t, but still give it a shot). Anecdotally, a lot of top-level athletes have cited this as being a game changer. Its basically just using your imagination. It can also be used to generate motivation on-the-fly. I sometimes imagine being back in highschool when in the weightroom or running.
I would argue that you would use it for work, in that some of the same fitness indicators are used to evaluate people in the workplace as in the sexual marketplace. Things like posture, BMI, self-confidence, and even the number of sick days you take factor in. Even height is a fitness indicator. It has nothing to do with actual job performance, but statistically is an advantage. It is pretty much undisputed that fitness is related to health.
However, your point is valid and something I have noticed before. People get their motivations for fitness in different ways. I suspect it may have to do with extrinsic vs. intrinsic motivators?
