This has me thinking about how many of my own changes were paired with insomnia. I'd lay awake at night knowing that I wanted to do X. That was usually easy for me to see. But then I'd realize that doing X meant giving up Y where Y was something that had previously been my passion and a big part of my identity.

I switched from basketball to running in high school. That was a long night realizing that I was going to quit one team to be all in on another. I used to be a programmer and now I really am not. I ran a coaching and publishing business from my pool and was telling people I was half retired. Now I work nonstop and a lot of that work is in spreadsheets. You're right that it's healthy to expect to give something up, i.e. let it die.
