Do you have any work week organizational tips or tricks?

I work in a busy production business, and I am constantly inundated with meetings, approval requests, and project resolutions. I am asking my fellow Jellies for some work week organizational tips or tricks. I need to schedule updates on my Outlook calendar with “me time”, in an effort to catch-up on my heavy workloads.
Please share with me some recommendations on some of your ideas on how I can schedule some time on my calendar to let my team know that I am “busy”, but in reality I need a break from the constant chaos that sometimes surrounds my executive position.
