what if i sit in front of a wall and just stare the whole day at the wall?I don't think there is necessarily anything wrong with habits. When you learn how to drive you form habits and then it frees some of your mind to pay more attention on the road and drive more safely. You also make habits on what are the things that you need to pay attention to and what things you can ignore, which is very good when you drive.
But you are probably talking about what they say around mindfullness, that we do some things out of habit and without paying attention, we react automatically without being mindful, and then we make the same mistakes over and over for example, and our lives run by without being lived. I agree it is good to be mindful about stuff, but we cannot be mindful about absolutely everything, this is just impossible. We can prioritize our attention and habits help us to do that. Also habits can help us achieving stuff using less energy and less effort. But we can be mindful about how we use habits, we don't need to let them govern us.
yes for the rest of my life
