I use Things3 loosely, mainly for (reoccurring) reminders, also keep my shopping list and things like that in there. I also use it for work tasks, but not a lot, I don't like endless backlogs I will delete things that sit too long. I generally remember the important things. I also use "remind me" in Slack a lot as most stuff arrives there. For me it's often just a case of "postpone till after I complete what I'm doing". I use Google Calendar for appointments, birthdays etc, work wise I'm stuck with Outlook calendar, it's fine, works well to schedule meetings etc.
