I have never had a lot of money. But I don’t believe you have to have a lot for it to become burdensome. Money has always seemed to be a burden. Either you have it and the obligation and responsibility becomes a burden (so I’ve been told, ha) or you don’t have it and life without money becomes a burden. I guess money became a burden to me when I started paying my own bills.
Let me explain. I raised my 2 girls by myself. I was fortunate to have a good job as an office manager for a doctor in Dallas. I was able to pay my bills and juggle things around to afford what the girls needed for school and what not. When I didn’t have money for something they wanted I felt like I carried the world on my shoulders. I didn’t let them know how stressful it all was because I felt like it was none of their business. They were kids and needed to be kids. They would soon enough be feeling the stress of managing their own household and shouldn’t be asked to help shoulder that burden as kids.
Once, me and my youngest daughter, who was an adult at this time, went to a drive in fast food place and got a couple of drinks. My daughter was treating me and when the car hop came to deliver the drinks, my daughter gave her $5.00 as a tip, which was more than the drinks! I, of course, asked why she did that and she told me that they live off their tips and she knew what that was like having been a waitress before. I said something about her needing the money as well and how money makes the world go around. She said “No, Mom, you can be dead-assed broke and the world is still going to go around.”
That was when I quit letting money be a burden.
