I like that quote!
It’s true an individual can change the world with one realistic goal at a time. Personally, I have yet to figure out how I can do that.
Shooting for the stars can be an escape, but without it, we’re limited. People don’t know their own potential. That’s why it’s important not to be encumbered by what we accept ourselves to be. It may be who I am today, but no-one knows how far they can go tomorrow. Don’t get lost dreaming of stars though. You may miss the ship when it takes off.
