To Do Lists and Planning in a Corporate job


I need some clarity how do you juggle priorities, planning and getting rid of To Do lists when working in a corporate office? Obviously work days are more structured and I don’t have as much control over it. My days seemed to be filled with meetings too. If I don’t keep track of the things that need to be done I feel like I will forget about it. Do I keep a list somewhere and just schedule time with myself on my calendar to focus on the important items? Do you use a physical planner? If so is there one you recommend?
