Investment is the totoal amount of time, energy, money and efforts.

It can be invisible or visible. We always invest in our wants, needs and desires of diverse aspects.

I like the concept of the investment in the relationship. Lots of times, wants, needs and desires come into conflict while the inner and outer enviornment are interacting, however, we still have to decide where to invevest our time, attention, energy, efforts or money.

Most important of all, we tend to expect a promising long-term values instead of short-term profits.
