Business has no emotion

I took my silver and gold in to the dealer to liquidate it today. An odd thing happened. I was really kind of sad to sell them, even more so than selling the car I have yet to do. How can I get attached to some shiny little coins? I did eventually train myself to look at most things as business when I purchase them, in reference to initial price, expected profit, max loss potential, etc.

The point is this, if it is a deal to make you money, it is just that. No emotion, no like or dislike, just the question of 'Can it make me money?' If the answer is yes then buy the deal and get it done.
