Focus is a word that is often used to refer to concentration. If your main focus is on graduating college as a doctor then this is what you will concentrate on while you are in school, spending your time studying and learning rather than drinking and partying. Focus can also mean something that is the exact center of your attention, such as being the focus of a criminal investigation.
You must tell yourself, 'No matter how hard it is, or how hard it gets, I'm going to make it.
You will face many defeats in life, but never let yourself be defeated.
Be yourself people don't have to like you and you don't have to care.
Maybe not today, Maybe not tomorrow. But somewhere down the line, there has to be a light.
