“That’s just the way that I am.” Ever find yourself saying this, when confronted about something you’ve done? If so, that means four things: (1) you are being unreasonable; (2) you KNOW you are being unreasonable; (3) you are making the conscious decision not to change what’s unreasonable; and (4) you don’t care about the effect your unreasonable action has on others.
The upside is, if you are saying this, you have the capacity of self-reflection. And it’s never too late to ditch this axiom, and a philosophy that causes others, and you, unhappiness.
