Always desire to learn something useful.

It's always too early to quit.

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

If you've got a talent, protect it.

Be gentle to all and stern with yourself.

Go for it now. The future is promised to no one.

If you think you can do it, you can.

By failing to prepare, you are preparing to fail.
