The Perfect is the Enemy of the Good. We hear this saying a lot, probably to the point that we miss the lesson – if you seek perfection you'll likely fail, and miss the chance to do things that are good.
We also are very familiar with people who lie to themselves and others about who they are. They conceal interests, religious affiliations, sexual orientations, etc. We know such people – or are such people – and know they're miserable.
You can't hide from yourself. The perfect is the enemy of the good. These two things go together in the hard fact that you can't be perfect – especially someone else's idea of perfect.
