A point in which the rays of light meet, after being reflected or refrcted, and at which the image is formed; as, the focus of a lens or mirror.
A point so related to a conic section and certain straight line called the directrix that the ratio of the distace between any point of the curve and the focus to the distance of the same point from the directrix is constant.
A central point; a point of concentration.
To bring to a focus; to focalize; as, to focus a camera.
It is during our darkest moments that we must focus to see the light. Aristotle Onassis
Successful people maintain a positive focus in life no matter what is going on around them. They stay focused on their past successes rather than their past failures, and on the next action steps they need to take to get them closer to the fulfillment of their goals rather than all the other distractions that life presents to them. Jack Canfield
Live life to the fullest, and focus on the positive. Matt Cameron
When you focus on being a blessing, God makes sure that you are always blessed in abundance. Joel Osteen
You can't depend on your eyes when your imagination is out of focus. Mark Twain
