To know oneself, one should assert oneself.
Things do not happen. Things are made to happen.
Begin to be now what you will be hereafter.
Problems are not stop signs, they are guidelines.
The secret of getting ahead is getting started.
Either you run the day or the day runs you.
If you can dream it, you can do it.
Only the educated are free.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
It frequently happens that two persons, reasoning right on a mechanical subject, think alike and invent the same thing without any communication with each other.
