It's always too early to quit.
If you're going through hell, keep going.
Be thine own palace, or the world's thy jail.
I can, therefore I am.
Without hard work, nothing grows but weeds.
If you can dream it, you can do it.
Well done is better than well said.
Either you run the day or the day runs you.
If you think you can do it, you can.
To know oneself, one should assert oneself.
Now it is quite clear to me that there are no solid spheres in the heavens, and those that have been devised by the authors to save the appearances, exist only in the imagination.
