Another aspect if integrity is being true to oneself.
But do not mistake selfishness for being true to oneself.
It is easy to confuse the pursuit of selfish desires with being true to oneself.
You may pursue the things that bring you pleasure, and that may constitute being true to oneself.
But, depending on what those things are, it may just as easily be unbridled hedonism.
At the same time, too much self-discipline can be a form of unkindness, and taken to an extreme it can squash the spirit.
But this is far less common than the lack of self-discipline that pervades our culture.
To be true to yourself, you must live in a way that sustains your body.
If you do not respect your body, your spirit will be degraded.
Ignoring your physical host eventually leads to physical pain, and too great a burden of pain can lead to depression, sap the will to live.
“But shouldn’t it be a matter of personal choice if one wishes to allow their body to degrade?” I hear you saying.
The answer is that it is not, because physical deterioration rapidly becomes everyone else’s problem.
Diabetes, heart disease and obesity, degenerative arthritis- these things prematurely deprive a person of their self-reliance, and instead of being a contributor the greater good, a person who should be a happy and productive member of society becomes needy, and costly.
There are, of course, individuals who suffer ill health through no fault of their own, but they are by far the minority of unhealthy ones, and we have an obligation to treat them with compassion.
Thus a life of true health becomes your obligation. You do not have the right to inflict the consequences of your selfish desires upon the people around you.
