Honesty is the first chapter in the book of wisdom.

Everything else depends on an accurate starting position. Judgement built on a flattering account of your own situation will be sophisticated and wrong, because the reasoning was applied to figures that had already been adjusted. Being straight with yourself is not a virtue added on top of thinking well, it is the precondition for it.

Find the number or the fact you have been rounding in your favour: the money, the drinking, the state of a relationship, how the work is really going. Write the unflattering version down. Everything sensible you might do next starts from there.
