Answer:
Mindless decisions can cut down time that could be used for something else and overthinking starts to come into the equation as well and we will talk ourselves out of the decision all together.
Step-by-step explanation:
A decision will become "mindless" if we repeat it often enough to the point where it become a hobbit. This actually could safe you a lot of time compared to putting a lot of thought
For example, let's say that you have to eat breakfast everyday on 7 PM.
If you make a rabbit of eating oatmeal with milk every single day, your body will mindlessly get that exact food every time at 7am. But if you don't you will have to spend a couple of minutes thinking about what breakfast you should eat today .
