There is a fine line between you owning money, or money owning you. Which can be easily crossed without you realizing it. Because of the constant desire to want money to come to you in many ways, you can get lost in that quest and make yourself, perhaps, an ambitious person. That's where the money would be possessing you, and being your master, a terrible master by the way. When this happens, the desire to have money, to become someone with wealth, can cloud your mind and become your highest priority.
On the other hand, money can be an excellent servant. When you're the one who owns it, it can help you achieve unimaginable things, when it works more as your tool and not your reason for living. That way you won't feel like you're leaving a part of your soul behind whenever money is involved when you lose or not earn what you expected.
Our relationship with money will also be important to work on, in addition to learning about our work, our finances, or knowledge in general, there are also things to study in our direct relationship with money, that can be found in books, Internet, or other sources of information.
