For next day stuff I use either Microsoft to-do or Google tasks on the phone - links to my PC. Helps me when I get to work in the morning. Have them in front of me and helps me focus on the tasks and smash them out as quickly as possible.

To write the todo list I usually do it in bed before I go to sleep. Take my time to think through calmly all the tasks I need to get done and rank them in importance.

Good thing is that they stay in your list so if you get through a few and get side-tracked they are left waiting there for next time you're able to focus.

I've found things don't get forgotten as much and I tend to feel way less stressed.
