Begin to be now what you will be hereafter.
To be a good loser is to learn how to win.
If you think you can do it, you can.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Go for it now. The future is promised to no one.
Only the educated are free.
Who seeks shall find.
It's always too early to quit.
I'd think learning to play the guitar would be very confusing for sighted people.
