I too group like with like when it comes to task management. I have many emails to process, tasks to oversee for other teammates, QC to perform on work being completed, and I contribute to individual cases within our practice. To help make sure I am being thorough when in a particular matter, when I take up any single task, I also review all my platforms (email, case management software, notes, meeting agenda updates, team chat messages, etc.) so I am working on the same file across all platforms so I don’t have to switch brain gears.
I also just began starting my workday at 5AM with a two-hour focus block really gets me into the right mindset and then the rest of the day tends to flow smoothly (note I posted a comment to another thread about how overwhelmed I have been, so this is a VERY new development for me).
I do not batch my meetings, but rather do everything necessary to close out any action items immediately following the meeting while it is still fresh in my mind, so my calendaring app (Calendly) has generous buffers baked into every meeting. When manually scheduling I am very protective of my time (a luxury since many people don’t get to decide how many meetings they want to take in a day, or how close together they may be).
My favorite, though, is probably ruthlessly culling spam by unsubscribing, etc. I love doing that! It may not save me time today, but over time it helps reduce clutter and noise, and I can process my inbox down to zero pretty regularly.
