Everything in life is an exchange.
For our side of the bargain we can put up; money, effort, time or thought. Even watching a meaningless T.V. show is an investment of our time in exchange for hours to pass more fluidly.
Every thought you have had, or now have, you have purchased with your time. We all pay for our acquisitions with something or somethings that are dear to us.
We are paying for every person or thing to which we have any connection.
If you are paying the fiddler . . .
Make sure he is playing your tune.
