Time is spent, and unfortunately never replenished.
Unlike a bank account, where you can take money out and deposit more back in, time keeps moving, never to be refilled.
Instead of developing a habit of filling up every minute of the day with appointments and events, try building in some flex time. Flex time would be time for yourself - whether there was spill over from another appointment, time needed to catch up on outstanding items, time for an urgent issue that popped up, or even time to catch up on industry material and education.
Time is finite - you control it. You need to manage it and not let time manage you.
