Be gentle to all and stern with yourself.
Never complain and never explain.
Go for it now. The future is promised to no one.
Leap, and the net will appear.
I can, therefore I am.
Who seeks shall find.
Either you run the day or the day runs you.
To be a good loser is to learn how to win.
Begin to be now what you will be hereafter.
The most effective way to do it, is to do it.
I'd think learning to play the guitar would be very confusing for sighted people.
