The hardest person to be honest with is yourself. There's always a comfortable version of the story — the one where the problem is the timing, the other person, the circumstances. Anything but the part that's yours.
The comfortable lie protects you in the moment and costs you everything slowly. You can't fix a problem you've filed under someone else's name. Self-deception is the one con where you're both the trickster and the mark.
The truth about yourself is usually less flattering and far more useful. It's the only ground you can actually build on.
