It does not matter if you are poor, rich to be a happy chap. All depends on your Mindset!
There is always a way to make you relaxed and happy no matter how bad the situation is.
This is a picture I took when I was in Philippines... the young naive girl was resting in a relaxed and satisfied mood in a hammock hanging between the crank of the Truck under the sun. It made me felt jealous ad I was wearing shirt cuff linked, sweating, carrying heavy note book going to visit a customer…. In my mind, all I had was how to start the talk and make successful sales pitching! Poor me versus and a Wealthy Girl!
