I was not feeling sorry for the money, it was just over 100 dallors and that's the money I can surely afford to lose. However, I felt bad for the irrational rush to buy things that I don't really need. It's like the money is manipulating me to spend it to prove that I have money. But hell no, I am not a show-off person and I am living just fine with my life.
So what the point is? you seems to contradicts one to another, but you're already realized about it lol.
As long as you're already afford $100 to lose, I don't think you need to think you're using that's money without a point and regret after that. The fact you still have a lot money and you've own a lot things, which mean it's not hurt you and there's no problem to spend small money for self reward.
Money management is a must, but don't forget to enjoy your life.
