I’m writing my PhD and sometimes feel like I’m losing my mind trying to balance home and work tasks, thesis tasks, personal and household habits, and potential connecting these to notes. I really struggle if everything isn’t in one place I can’t keep track of it.

I’ve been using Beaverhabits for habits, Baikal for Caldav connected to iPhone reminders and Thunderbird tasks, and memos and trilium for notes. I also, use a notebook for daily stuff and move it over to digital if it isn’t finished by 5.

Any recommendations? I would really appreciate it. I enjoy thinking about how to do and manage work efficiently but also need a firm system.
