"Happiness depends upon ourselves." —Aristotle
I was speaking to a young professional who seemed to be doing well in his career. Everything was going well for him, and I was delighted with his progress.
He rarely went out of a job in his 8-year career and had a consistent income to look after himself and his family. He also recently got an opportunity to study abroad, which significantly boosted his career.
Despite all this, he has remained unhappy.
