What if you're practicing wrong? Then you get very good at doing something wrong.
Practice is the path of mastery.
Perhaps we'll never know how far the path can go, how much a human being can truly achieve, until we realize that the ultimate reward is not a gold medal but the path itself.
Education is... doing anything that changes you.
To learn is to change.
Perhaps the safest prediction we can make about the future is that it will surprise us.
