Be gentle to all and stern with yourself.
If you think you can do it, you can.
The secret of getting ahead is getting started.
You never know what motivates you.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
To know oneself, one should assert oneself.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
Responsibility for learning belongs to the student, regardless of age.
