Taking detailed notes in meetings, and keeping a record of what I'm doing/thinking about has allowed me to drastically shorten the "context switching time" between meetings and days. And having those notes is vital every once in a while, ie: X person said Y thing on Z date. Or It took me X days to do this thing, etc... doing this is a great way to be "management material" if that's what you wanna do. Because you are visibly very organized.

I literally just write down everything important in meetings because it keeps me focused and I enjoy the act of hand writing.

And then I keep notes in a giant endless .md file of what my goals are for the day. It's like 10 lines per day max.
