Micro-retirements
Generalists sometimes need to take things "off the table" in their lives, sometimes permanently. A micro-retirement is the letting go of a single activity in your life to make room for other things. I've found that using the mindset of retirement is more acceptable, psychologically, than "forcing myself to quit" or something like that. "Quitting" implies dissatisfaction, which is why I never considered "quitting" parkour. "Retirement" implies completion, which is, at worst, bittersweet.
