Re-writing thoughts around time

I want to re-write my beliefs about time and constraint.

C: Time
T: I don’t have enough
F: Anxiety
A: Scattered attention to things (skip from think to thing without completing things)
R: Don’t complete things and confirm belief that I don’t have enough time

C: Time
T: I have plenty of time to do what I really want to do
F: Peace
A: Plan, use, create, enjoy
R: Accomplish what I want and confirm belief that I have plenty of time.

I don’t know how to get between these models. When I try to move to the intentional model, I am unrealistic about my calendaring thinking I can get more done in the time I have. Then I reinforce my original belief. When I’m in my old model I’m stressed out all the time. Help! Constraint is something I’m really challenged by. When I try to constrain I constantly revert back to stressing that I’m not getting everything done that I want to and there is not enough time. I worry that I will make the “wrong” choice with my time and be disappointed later.

I’d love some insight into this. Thank you!
