This is a great way of thinking, and I agree. Although I should add it's still a bit naive and you may grow up to realize that.
Of course it's naive, but I may as well continue to believe it while it rings done degree of truth to me personally.
I want a tablet. But every time I think about how far that money can take me, I give up. Price iPad ~ Price TransSiberian ticket ~ Price return flight to NYC.... etc... it's a pretty easy choice for me.
It's personal choice. Some people like travelling, some people like jewellery, clothes, gadgets etc.
