Sounds very hard actually. If you asked me to spend a significant fraction of Bill Gates' money I wouldn't even know how to begin.

How would you do it? Do you have a way to earn his trust, a service to offer him that he values a lot, a way to steal from him, or anything like that?

Melania apparently managed to do it with true love and kindness. Are you capable of sincerely loving Bill Gates for a period of several years, or fake it in a perfectly convincing way for several years?
