Some walk because they have to, others walk because they want to. Both walk, but the motivation is different.
We often forget the privileges we enjoy, thinking the world is as we are. Of course, each experience is subjective, and each one of us will have different experiences, starting points, things that we can do or not do by default etc.
When we take a moment to stop and observe, however, it will make us aware of the richness of live. The pain and the joy hidden in plain sight, and of the many things we take for granted.
We are lucky to be alive in this moment, for life is not guaranteed for anyone. And what a beautiful life it is.
