How do you choose what to do during deep work every day?

I update and prioritize my to-do list daily, first thing when I start my work day. Then I simply pick the most important task and start my deep work session until lunch, when it's easiest for me to focus.

The toughest thing that is important to me. Whatever I know I need to do that I may not feel like doing at any given moment.
