I agree; regimenting your day is a poor substitute for short-term planning. It looks very orderly to have items like 9:00am, read email, 9:10am, Make sure Jira tickets are in correct states, 9:20am, respond to email, etc., filling your calendar from now until eternity, but it makes more sense to spend ten minutes at the end of every day planning the start of the next. Maybe you know your Jira tickets and email are in order and you can sleep an extra half hour. Maybe you have an important presentation in the afternoon and it would be best to spend 8am-9am nailing down the answer to a question you know will come up. It's very hard but very important to stop working a few minutes early at the end of the day. You want to keep coding (or whatever) right up until the minute you need to stop, but that leaves you unknowingly disoriented at the start of the next day. You will either pick right back up with the coding, forgetting about everything else, or start aimlessly and waste the first hour of the morning trying to restore your awareness of priorities.
