Personality is what makes us all different. We all like different things, and we all have some things in common but everything is rare. Personality can affect our decisions and choices in many ways. First, if you are truly a nice person and you find a 20 dollar bill on the ground in front of your teachers desk, would you take it? Or would you place it back on the desk? Personality has a lot to do with whichever you choose. Be careful, though. Sometimes making the wrong choice will change peoples opinion about you or change the way the feel about you!
