Happiness at work is all about your attitude towards that job according to a Columbia University professor. We often think that we have little or no choices at work. We think that we are powerless and that someone else has all the control. We wait for something outside ourselves to make us happy, a pat on the back from the boss, a promotion or pay rise. But it’s what is going on in the inside that counts. How we think about our job has a huge impact on what makes us happy or unhappy.
