If you think you can do it, you can.
Without hard work, nothing grows but weeds.
Never complain and never explain.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
After a storm comes a calm.
Be kind whenever possible. It is always possible.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
The doubt of an earnest, thoughtful, patient and laborious mind is worthy of respect. In such doubt may be found indeed more faith than in half the creeds.
