If I literally had all the money in the world, it would be too much. So I would give a good amount away. But only to people that have earned it. For example, those who believe in "sharing the wealth" can live off the land with no help from me. I can picture their retaliations now. "But I am a human and you should help me because we are equal. We all need to be treated equally." Awww.... Such a wonderful argument (sarcasm). They need to do better than that to get anything from me.
For the rest of the money, I would get 3 master's degrees, 2 bachelor degrees, have my dream house built (6 bedrooms with an indoor garden, full kitchen, three full bathrooms, and a few visitors buildings outside that fit under the 144 ft requirement by law), I would also get my family a few little gifts, my boyfriend to pay for the rest of his education (only three classes) and get him a new car and bike. Also I would travel the world with a month long vacation each year and become a author.
