Common sense is the collection of prejudices acquired by age 18. The supreme happiness in life is the conviction that we are loved. Between two evils, I always pick the one I never tried before. Nothing is as inevitable as a mistake whose time has come. I have often regretted my speech, never my silence.
Good judgement comes from experience.
Experience comes from bad judgement. For every complex problem, there is a solution that is simple, neat, and wrong. Sort of been there. Sort of done that. Woohoo is the expression, I think.
