If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
You never know what motivates you.
Be kind whenever possible. It is always possible.
Only the educated are free.
Be gentle to all and stern with yourself.
Because of my medical and ideological training, I am accustomed to saying that life is adaptation and symbiosis.
