The excitement of buying something is real, but it is fleeting. We don't have to wait for life to hurt too bad to stand it, before we decide to make a change. I'm not saying that all possessions are bad or that money is bad. Possessions are neutral. They are just things.
Money is a tool.
But possessions or money will never fill the place inside us that God put there. It can only be filled by a relationship with Him that will provide us with purpose. Yes, a career, a job, a way of making a living is important. There is a job out there we will love enough, that doing it will not be a chore but a joy. Maybe when you were a child, you had a dream of what you wanted to become.
