“Believe you can and you’re halfway there.”
I think that what Mr. Roosevelt meant when he said this was that you cannot achieve your goals if you don’t think you’ll meet them in the first place. One major way I can apply this to my own life is when I rock climb. I know that when I have to reach far for a hold, I sometimes think I can’t do it, and then fall. If I keep the positive attitude Roosevelt suggested, I’m sure it will help me climb better. This quote could change someone’s attitude by showing them that they have a chance at everything. If this thought spreads from person to person, it will eventually fill the whole world. Then, more people will have positive attitudes and try things they thought they couldn’t do.
