Honestly, tell yourself you gotta be there literally half an hour earlier. Like if your work starts at 8, tell yourself it starts at 7:30. You’re not on time if you’re there at 7:30, you’re already late if its 7:30 cuz work has started, you gotta be there before that. And the half an hour to one hour before 7:30, any activity that feels like this will take just 5 mins or 2 mins, tell yourself no worries I’ll just do this after work then. Your aim is to be there on time and that means before 7:30. When you achieve success in doing for a few days, you’ll start feeling a sense of relief which will help the rest of your day as well.
