Well, everyone has feelings, the only thing that varies is how different people handle them. "Tough people" will isolate themselves from feelings, keeping them buried deep inside them, while others might not have a way to express them, so they get nowhere anyway.

Although I don't have as many feelings as it might seem, I find emotions to be a great source of inspiration most of the time.
