Only the educated are free.
Problems are not stop signs, they are guidelines.
Without hard work, nothing grows but weeds.
After a storm comes a calm.
Know or listen to those who know.
It's always too early to quit.
To know oneself, one should assert oneself.
To be a good loser is to learn how to win.
You never know what motivates you.
Be gentle to all and stern with yourself.
As my dad said, you have an obligation to leave the world better than how you found it. And he also reminded us to be givers in this life, and not takers.
