If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
It's always too early to quit.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
By failing to prepare, you are preparing to fail.
Never complain and never explain.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
I can, therefore I am.
There is as much wisdom in listening as there is in speaking - and that goes for all relationships, not just romantic ones.
