Things do not happen. Things are made to happen.
If you think you can do it, you can.
To know oneself, one should assert oneself.
After a storm comes a calm.
Problems are not stop signs, they are guidelines.
Be thine own palace, or the world's thy jail.
If you can dream it, you can do it.
Expect problems and eat them for breakfast.
What you do today can improve all your tomorrows.
Begin to be now what you will be hereafter.
That is a secondary teacher conception - the writer as an observer.
