That’s an impossibly complicated, unknowable question. Some better questions:
“What’s bringing me joy, today?”
“What’s bringing me apathy, today?”
“How can I do more of the former and less of the later?”
You don’t need any answers–simply ask the questions.
I suspect that towards the end of your life you’ll look back on a pattern that emerged out of these questions, and what you should have done with your life is exactly what you did.
