It's called time blindness. It can affect you either way, putting you super behind, and late, or super early.
Our brains don't understand the concept of time. Your brain can't keep track/comprehend how long it will take you to do anything from how long it takes you to brush your teeth in the morning to how long getting to a new place will take. So we cope with either admitting defeat and be late, or giving ourselves waaay too much time to get there early.
Tiimo is an app designed for time blindness. Im not 100% in love with it, but I do like it most of all the routine apps I've tried.
Doing your own research into time blindness will also help you get a better understanding of it than my butchered summary of it 😉
