If you need to do something over and over again, many times on a repeat it's better to have a routine for that. Repetitive tasks are boring. It's better to be able to do them without thinking.
I have many routines. For example my mornings are quite well laid out. I wake up, dress, go to bathroom, make coffee, feed cats, sit down to write these posts and enjoy the coffee and so forth. It takes me 55 minutes from bed to door. Mostly I don't even think about what I'm doing. I think other things, like what to write today, what's waiting me at work. More important things than having to think about did I already brush my teeth.
Having a routine for those kind of tasks help. You know exactly what you need to do next. You do all the steps, no need to think if you have forgotten something. You know how long it will take. You don't have to waste a thought about it. You can even spend that time thinking something else. You can free your mind from the boredom.
Making decisions is expensive. We spend way too much time on deciding what shirt to wear. Why not just pick the topmost from the pile, or just have all the your shirts the same kind.
Not having to think about boring, meaningless stuff can make you a lot more efficient. Saves your mental energy for the meaningful decisions and leaves more time to think about interesting things.
