Be gentle to all and stern with yourself.
Without hard work, nothing grows but weeds.
Be thine own palace, or the world's thy jail.
Go for it now. The future is promised to no one.
To know oneself, one should assert oneself.
Always desire to learn something useful.
You never know what motivates you.
Problems are not stop signs, they are guidelines.
Who seeks shall find.
Know or listen to those who know.
Wisdom alone is true ambition's aim, wisdom the source of virtue, and of fame, obtained with labour, for mankind employed, and then, when most you share it, best enjoyed.
