I choose #1 "Believe you can and you're halfway there." by: Theodore Roosevelt because it means the same as never give up to me. I could apply it to my life by working hard on everything I do like school and sports. It could make a positive change in someone's attitude by giving them hope. Like if a math test is sopposed to be really hardI could tell them they can do it. It could make an impact on the world by more things getting done. That is why I choose #1.
