Sevens frequently have a slight or pronounced weakness for starting projects with great enthusiasm and then not finishing. I am a Seven and here is one thing I found quite effective. I shut drawers. Yes, I would get something from a drawer and then go on to my task and leave it open. I resolved to close all doors and drawers behind me. It really surprised me how foreign and strange it felt to close them. But it made a significant difference in my finishing. This was years ago. Now my technique is to include on my “to do” list one or two things I will finish. Not just any assignment, but to finish an assignment I’ve made myself or project I’ve begun. It works. If you’re a Seven, try it. But it doesn’t work as well as closing drawers.
