Have you ever had your friends, or even better, your kids, help you with a project? It can be a lot of fun but the “productivity level” is not always as high as it could be.
It seems that especially in aviation, the more people show up to “help”, the more the project is getting discussed rather than actually worked on. I seem to have walked away in the past with the aircraft looking exactly like it did in the morning. But somehow I was many opinions, thoughts, ways, and ideas on what to do and exactly how richer 😉
