You’ll encourage friends to get more money
Once you have that wealthy mindset (and bank account), you want the same for your friends. Once you’ve experienced what it’s like to not check menu prices before ordering, you want that freedom for your loved ones. Also, once you make more money, you realize how underpaid you used to be, and from your position, you can see how underpaid your loved ones are. This might be when you start encouraging your friends and family to ask for a bigger salary or a bigger raise, or to quote a higher price for a client. It may worry them, but you’ve seen how the risk can pay off.
