Until you spread your wings, you'll have no idea how far you can walk.
There’s no shame in being a flightless bird. The red rail, the Chatham duck, the great auk: all beautiful. And all extinct.

Because there's nothing standing between you and your goal but a total lack of talent and complete failure of will.
