More advice from another taxi driver

My boss (aka The Wife) takes the cab rather than drive her own car. One advantage of that are some of the priceless words of wisdom (mostly unsolicited) from cab drivers. Here’s one more she received today.
The taxi driver was a retired civil servant who was a team leader. He knew all about dealing with Gen X staff and baby boomers. An early advice he gave to his younger team members was the 3 Hs.
He would counsel that regardless of one’s position and job status, always remember this route to career success: Happiness, Health and Humility.
Do the job and activities that make you happy. And do them happily. Always take care of one’s health and not let the job affect your health – and vice versa. The most difficult one is humility.
Mr Cab Driver had worked with graduates, scholars, and Type As, amongst his many colleagues. A lot of people would indeed pursue job and personal happiness. They would also worry and take care of their health.
However, when it came to eating humble pie, being simple and grateful, there was a sudden lack of self-awareness. Mr Cab Driver noted that the ones who rose through the ranks, AND were happy and healthy in their jobs for a long time, tended to be those who were humble and less self-serving.
Humility moderates extremes. It is a righting mechanism for our words, actions and thoughts.
Good advice, but the cab fare was still expensive.
