Unable to plan

C planner
T I don’t plan properly and I don’t stick to the plan I made
F overwhelmed
A dwell in confusion
R achieve less

C planner
T just stick to the plan the moment ur aware of overwhelm
F aware
A do the timed activity
R achieve more

I do realize that I need to micromanage my planner . But every time I look at my old to do list (which I kept)and all those things which I didn’t do , I find evidence of how useless I’m . How do I get better at achieving in the moment
