This reminds me of a life philosophy.

If you dislike a situation you're in and you try and fix it by switching to a new situation, you'll generally bring with you some of the problems that created that prior situation.

If instead, you bit by bit improve the situation until you feel at peace with it, you'll then either no longer want to move to a new situation, or if you do want to move, you'll no longer bring with you the problems of the prior situation.

Applies to job changes, relationships, projects, goals. And, from OP, applies to architecting software projects.
