It's always too early to quit.
The secret of getting ahead is getting started.
Problems are not stop signs, they are guidelines.
Things do not happen. Things are made to happen.
Go for it now. The future is promised to no one.
Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
Well done is better than well said.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
I studied with a blind teacher from about 5 until I was 16, at two different schools. From the age of 12 until 16, I was in a boarding school-which, I believe, at that time was compulsory for blind children.
