If you're going through hell, keep going.
If you can dream it, you can do it.
What you do today can improve all your tomorrows.
The dog that trots about finds a bone.
Do not weep do not wax indignant. Understand.
Without hard work, nothing grows but weeds.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
Expect problems and eat them for breakfast.
Never complain and never explain.
The capacity you're thinking of is imagination without it there can be no understanding, indeed no fiction.
