What does it mean to be defeated?

I think the quote by Maya Angelou is needed reminder in todays world of stress that is centered around sports and grades. Now when people get bad grades they think there life is over and that they will not get into the college they had always dreamed of. Maya is trying to say take these defeats and do something about them. Do not wallow in your own self pity, but instead be inspired to do better than last time and rise to the occasion the next assessment you have. You were defeated that time and it will happen a lot in your life but its what you do after your defeat. What it means to be truly defeated is after something bad happens to you, you lose your drive and inspiration in what you are doing. Instead of doing something about your defeat you accept thats how it is going to be the rest of your life. I have fallen victim to this many times and I need to be able to learn from my defeats and instead being crushed by the defeat I have to be able to learn from my defeat.
