I am grateful for living in a world where anything is possible.

Anything isn't possible. You will not be a fighter pilot at seventy, and pretending otherwise doesn't help anyone.

What's true is stranger and more useful: the number of doors genuinely open to an ordinary person right now would have looked like fantasy three generations back. You can learn a language from a phone, talk to someone on another continent for free, change careers at forty without social ruin.

The limits are real. They also sit much further out than the ones we tend to enforce on ourselves out of habit.

Name one thing you've filed under impossible. Check whether it's impossible or just unattempted.
