I don't see how you need to reconstruct your personality to avoid tinkering with things. Just don't do it. I'm a tinkerer too; all you have to do is realize that you have limited time and attention, and then consciously decide to focus your tinkering time on only specific projects, and ignore other ones. Make a priority list perhaps. This takes some willpower obviously, but it's no different than any other undertaking where you're deciding to make a change in your life and do something different (e.g., you decide you want to eat better, exercise more, try socializing more, act better towards people, etc.).
