Blood is thicker than water. And ego is thicker than blood. When a decision becomes part of who you are because you’ve emotionally invested in it, that’s a self-made prison in the making. It’s already becoming too hard to respond to new information by raising a hand, shrugging a shoulder and saying to yourself, “hmm, I didn’t do that very well, did I?”, or “what was I even thinking?”, or “you daft idiot, will you ever learn?”, or “I’m sorry, I was wrong”. And if in saying that while resisting any kind of justification, there’s not at least a glimmer of discomfort, it’s become trite and insincere. Lying to yourself or blaming others is much easier.
