I am the creator of my own destiny

Creating anything means working with material that has its own grain. A sculptor doesn't overrule the stone; they find where it will and won't split.

Your material is a particular body, a family, an economy, a handful of things you happen to be good at. None of it was chosen. All of it is workable.

Authorship isn't the absence of constraint — it's what you do inside one. The question isn't what you'd build with a blank block. It's what this one is actually for.
