If you think you can do it, you can.
Quality is not an act, it is a habit.
If you're going through hell, keep going.
The wise does at once what the fool does at last.
It's always too early to quit.
To know oneself, one should assert oneself.
Be kind whenever possible. It is always possible.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
Always desire to learn something useful.
Whoever incites anger has a strong insurance against indifference.
