They say the best things in life are free. It would be nice if that were true, and perhaps if you're talking about money, it has a ring of truth to it. However, it is the unfortunate truth that anything worth having has a cost associated with it, something we have to give up in order to have it. Many times it is money or resources, but even if it's just a positive interaction with another person there is a cost of some kind, be it time or effort. As with everything else in life, you get what you pay for.
