Nice! I just started doing something similar at work and came across Todist but I'm trying ticktick first - it integrates with my outlook inbox and calendar so it's easy to create email-related followups and such. Somewhat related to my personal life I put everything on my Google calendar. Important dates, plans, reminders, etc. It's the only reason I have any sort of grasp on my life.

Same with atomic habits I have some habit tracking calendars/notebooks but it's soooo easy to fall off and skip weeks.

ADHD is a real bitch sometimes.
