I treat relationships, health, and hobbies like projects that demand effort, and whose success is my responsibility.
They become a perpetuum mobile of self-efficacy. The more I invest, the more control I feel over my life. This builds momentum. This flywheel can only be stopped by a lack of kindness toward myself.
To make this work, I see the things important to me as malleable, and I see myself as someone who can shape them.
Since everything, including myself, changes over time, this is a never-ending cycle of improvement. Hoping something will stay the same is a futile fight against entropy.
So I embrace entropy as a fundamental truth and consider everything important to me as a fun project I get to work on.
Making an effort is never wasted.
