Managing time is a bit like a game for me. I have a work calendar, which stays relatively simple, and a set of personal calendars. Some of the personal ones are basically like the old paper ones many used to use: they store things like birthdays and anniversaries.
Some calendars, such as the social ones, are automatically generated- there’s one for Facebook, another for a travel site. Even Google now detects events in emails and creates calendar events on the same account’s calendar. That feature is pretty neat because I sometimes forget to go through my emails and create calendar events for social engagements, like concerts and conventions.
I’m not the best at time management, but I’m getting better at it.
