Never complain and never explain.
Who seeks shall find.
The secret of getting ahead is getting started.
Either you run the day or the day runs you.
Know or listen to those who know.
What you do today can improve all your tomorrows.
If you're going through hell, keep going.
If you think you can do it, you can.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
I'd think learning to play the guitar would be very confusing for sighted people.
