If you can dream it, you can do it.

If you think you can do it, you can.

The dog that trots about finds a bone.

Begin to be now what you will be hereafter.

It's always too early to quit.

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

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

Well done is better than well said.
