To know oneself, one should assert oneself.
Expect problems and eat them for breakfast.
Begin to be now what you will be hereafter.
Without hard work, nothing grows but weeds.
Either you run the day or the day runs you.
Only the educated are free.
If you're going through hell, keep going.
It's always too early to quit.
Be kind whenever possible. It is always possible.
Know or listen to those who know.
Don't take too much comfort in the fact that you're successful today because tomorrow could bring failure. There's no surety in life.
