I humbly submit that there is only one way to learn things: the hard way.
@codinghorror I think my favourite version of this is "good judgement comes from experience, experience comes from bad judgement"
@ianmackenzie @codinghorror a promising way out of this conundrum is that we can experience bad judgement of others; we are not alone. So I'd take it one step beyond:... Good judgement comes from the capacity to learn from experience of bad judgement; the capacity to learn comes from not being judged as one who won't learn! Not quite as snappy as The hard way!
