This Tibetan Singing Bowl "soundscape” on YouTube has been helpful for both focusing. I learned about it from the Library’s Mindfulness guide.
I have a tendency to try and do too much at the same time. I have many projects I need to complete, and think about them at once. So, to help keep me focused, I block out specific times in my calendar to do specific tasks. This forces me to concentrate on one objective at a time, set goals for that time, and plan out my work week. This helps me stay focused and on task.
I love planners! Confession: I buy more planners than I need, just because they are so cute. I also love to write things down as do-to lists. There’s nothing more satisfying than crossing out something that you’ve accomplished. I like to create two separate lists. I have a "day" do-to list as well as one that I look at with important future events. My biggest goal is to start off my to-do list with a few items and if during the day I have more time, I’ll add more things. I never add too many items because I don’t want to feel defeated if I don’t get to them.
Make a list and have it right in front of me. This is the list of stuff I need to get done that day. It needs to be what is necessary, and it needs to be realistic, (I’m probably not pumping out 10 lectures in a single day for example) but having a checklist of tasks for the day, and having it in a visible place where I can consult it throughout the day and show progress helps.
