Why do some people achieve their goals more than others? It's simple...they finish what they start! Far too often, people start goals, tasks, projects, ideas, assignments and never finish. And if you don't finish, you can't achieve your goals! I'm much more addicted to finishing than I am starting because I like closure. Without closure, I live with the heavy baggage of knowing I didn't reach my goal but more importantly, I broke a promise to myself. If I tell myself I'm going to do something, I do it.
Now, there's also a big difference between not finishing and deciding to never finish the goal. If finishing your goal is no longer relevant to you or someone else, than it's ok to decide to not finish. But at least you can delete it off your list and create closure. It's the things that are still relevant that are left dangling in your mind that you need to finish.
The biggest list of goals I have is probably my 43things.com list. It's the things I want to finish before I die and because I don't know when I'm going to die, I'm doing everything I can to do them quickly!
So there you go. Grab all those lists of unfinished business you have in your life and either delete them or finish them. Become addicted to finishing and you'll start achieving everything you want in life!
