I always do that. In fact, you just echoed my mind. There can be nothing more important than investing in oneself. But, I think, we must be vigilant before we do that, because most of the time, the capitalist advertisers create fake illusions of "Need". I prefer function more than the trend. And I believe in Warren Buffet's famous quote, "If you start to buy the things you don't need, soon you'll have to sell the things you need".
