On your link i cant see what kind of things were in his to-do list. As i know, his insatiable appetite for information drive him to devise a wide range of projects that are both challenging and exiting. The only problem is that he wrote everything reversed in mirror writing. And to read it you must be fluent in italian but also to have a mirror in which you’ll read his list. I’m not a fun of Da Vinci, but thanks to his efforts I started to use Mac Task Manager. It helped me to make my days easier and freer. Using a task manager, is the best option if you are interested for everything to go according your plan.
