Music for comparison
When I used to play a lot of music there were several characters who ended up being in 80% of my bands. They weren’t expendable or one time use. They were people that had work ethic, similar influences, and a drive to do the hard work of the project over and over again. Also, we knew each other, well.
I find that my experience with product development is similar. You will do much better finding a regular team to practice with then if you constantly start ground up on a per-product basis.
