To know oneself, one should assert oneself.
You never know what motivates you.
Well done is better than well said.
If you're going through hell, keep going.
It's always too early to quit.
Things do not happen. Things are made to happen.
Wherever you are - be all there.
The most effective way to do it, is to do it.
After a storm comes a calm.
Be gentle to all and stern with yourself.
To see what is right and not to do it is want of courage, or of principle.
To know what you know and what you do not know, that is true knowledge.
