Things do not happen. Things are made to happen.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
The secret of getting ahead is getting started.
To be a good loser is to learn how to win.
What you do today can improve all your tomorrows.
Always desire to learn something useful.
To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
If you think you can do it, you can.
It's amazing that something only an atom thick can be an impenetrable barrier. You can have gas on one side and vacuum or liquid on the other, and with a wall only one atom thick, nothing would go through it.
