Here is a good way to go through life: as if you live with a small dog or as if you are in an art museum. Either one requires you to look around before you move, before you take a step to see who or what your action will affect.
I've been in Europe for the past month which meant quite a few art museums. I was astonished at the number of people who back up to look at a painting and back right into someone because they didn't look around. They were just caught up in their own little worlds.
Because I live with a small dog (who thinks he's a big dog) I've learned to look around before I take a step. Before he came to live with us, Max lived outside all his life. He never lived around feet and ankles and legs and therefore did not how unpredictable they are. So it my job to look out for him.
I think this is an excellent way to live in the world, always asking myself if my words or actions are going to cause me to crash into someone or step on them. So yeah, go through life as if living with a small dog.
