Thank you, you answered exactly how I expected the answer to be: Saving this tiny amount of money is not sensible, at least compared to the money I should be expecting to earn with a STEM major. So get the most bang for my bucks I should spend it for experiences, as I planned it, or toys that I will use a lot.
So now I can look forward to feeling less guilty when spending my more or less hard earned money. ;)
On the other hand, although your current income is insignificant compared to what you'll eventually make, it's still significant now. In other words, it's still useful to save money now, because something-that-you-need-a-lot-of-money-for might come up before you start making big bucks. This certainly happened to me several times while studying, and when it did, I was glad that I had savings.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
