Problems are not stop signs, they are guidelines.

What you do today can improve all your tomorrows.

Always desire to learn something useful.

Be gentle to all and stern with yourself.

If you can dream it, you can do it.

By failing to prepare, you are preparing to fail.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.

If you're going through hell, keep going.
