Just a thought on how to implement this in Jello:
Create contexts called MIT and Goals and display these on the
Dashboard page. MIT could be Top Left and !Next culd be Top Right so
that your MIT's are always visible. When you do your Daily Review as
Leo suggests at Zen Habits you could assign the MIT context and it
would pop up on the List. Since you're only going to have 2 or 3 MIT's
it would be an easy fit on the Jello Dashboard.
Goals could be handled in the same way. Checklists - not so much but
you could do it in a Context also, just not a very clean
implementation of it.
I'm sure you've already thought of that but just mentioning it in case
you haven't.
