My sister is far far richer and more successful than I am. She once told me that every night the last thing she'd do was to make a mental list of things to do tomorrow. That was it. Nothing written down.
I feel there's more to the story. One thing is being organized, another is being able to execute consistently, and being organized is not a precursor to that. I am extremely smart, and productive, sometimes. Most of the times my mind jumps to random areas of interest, life happens, fight with wife/GF, parent illness, alcohol binges and I'm back to a baseline with almost no output. As if I'm sabotaging myself. Consistency is key, how you achieve it is second.
