Human nature is defined best by one single word: investment. Everything we do, all our actions and way of living are defined by our pursuance of a better life. This means that every second we spend living we actually invest in a future better image of our lives.
Financially speaking, investment, is defined by willingly giving away our current financial resources in the exchange for future better ones. This is why in the world, there are thousands of investment firms that specialize themselves in acquiring liquidities from the mases and investing them into massive projects, like hotels, airports or dams.
