“Just remember, you never know what's possible until you risk finding out.”
“Some things you can't find out; but you will never know you can't by guessing and supposing: no, you have to be patient and go on experimenting until you find out that you can't find out.”
“You never know just what you can do until you try.”
“Sometimes you don't even know what you want until you find out you can't have it.”
“As long as you believe it is impossible, you will actually never find out if it is possible or not.”
“I never understood until recently that it's possible to miss what you never had.”
