Wherever you are - be all there.
If you think you can do it, you can.
Be thine own palace, or the world's thy jail.
Problems are not stop signs, they are guidelines.
Without hard work, nothing grows but weeds.
Only the educated are free.
To know oneself, one should assert oneself.
It's always too early to quit.
Be kind whenever possible. It is always possible.
Do not weep do not wax indignant. Understand.
