Money is a tool and an amplifier. I'm sure we all know a person who is a jerk. Give them more money=bigger jerk. I also know good people who are rich and make valuable contributions to their community and society.
Wealth also allows you to buy back your time. Don't want to hand wash dishes, mow your lawn or clean your house? Buy a dishwasher, hire a landscaper or housekeeper and spend more time with the people you love or doing the things you enjoy. How much is your time worth? You, me and Bill Gates all have the same 24 hours in a day. How do you choose to spend it?
Your best skills can grow exponentially when the basic necessities of life are covered and you don't trade time for money. Andrew Carnegie was considered one of the wealthiest person in history, yet he gave away 90% of his fortune. Visit a local library and there is a good chance it was somehow funded by his legacy.
This is why I want to be wealthy and help educate others how they can do the same.
