Spending money

At somepoint, probably after I came to Australia, I feel bad when I spend money on some stuff. Stuff that I consider unnecessary. I think It was because my parents supports me staying in Australia while I'm in uni.

Now I don't feel that much probably because I have a job which pays me and have changes in my mind in spending money. I don't know whether it's good or bad, I don't know if this is just an justification on spending but I'm ok with it and felt good.
