Hello.
What you do in life impacts many people. You may never know who you'll impact but it will be felt. You make a decision to go into a field of study that will have tremendous impact. Your decisions impact not only you, but the world around you.
I make an impact by selling health insurance to people who need it. A person's health impact those around them. You make an impact every day and don't even know it. Make an impact every day.
