We often speak of what humans need to survive…you know, food, water, shelter from the elements, good health, and so forth…
I would add that having a purpose, having an aim, having some kind of ambition, be it ever so humble or grandiose, allows ourselves to grow intellectually, emotionally, even spiritually to discover more and more about what life is all about.
Without growth, I imagine we humans merely shrivel up and cease to be truly human. Maybe you have found your purpose or maybe you are looking for a new one…in any case, may you find it and explore it successfully.
