re: What's your Go-To Work Planner/Meeting Notebook

Padfolio, pocket memo pad, and Google Calendar.

Classic Franklin planner for everything in detail.
Use my phone for reminders.

I really like one like this but I have generally stuck with Moleskine.

I love keeping meeting records for future use/reference, so I can quickly go back to a customer meeting months ago and gain context. I do a lot of quoting in these records.

I picked up one of these a fee weeks back while traveling out of town with no notebook. It has been awesome for keeping track of meetings and attendees in a well organized fashion.

I use a bullet journal for all of my work in the field. Makes it easier to sketch an observation, quick drawings, track data, etc
