There is more to walking than your feet on the ground.
Yes, it is your feet on the ground, off the ground, on the ground again.
But walking require direction, an decision.
You choose a direction.
You decide to lift one foot off the ground and move.
The process repeats, and you are walking.
But while you are walking, there is a sort of living.
You are consciously moving in a direction of your choice.
Isn't that was life is?
So, life is like walking.
Life is like your feet on the ground, off the ground, on the ground again.
First there is breathing, then there is thinking, then there is moving.
And in between, living.
