Could you become arrogant or over confident if you won over $100 Million in the Powerball Lottery?

My user name beta_nerdy is a perfect description of my personality. I am passive (beta) and a true nerd. I have been called lots of names during my life and bullied and ostracized by countless people. I have always been walking on needles and pins and have tried so hard to be accepted and liked. Outside of Reddit, I am very cautious and timid and afraid to speak up for fear people will take everything away from me.

But I ask myself if I would change when I win over $100 Million in cash after taxes in the Powerball Lottery.

If you suddenly have over $100 Million to your name would you now have a devil may care approach with people, become arrogant and overly self-confident? (Because you won't have to please anyone anymore, they will try to please you!)
