You need to manage your risk. Without a risk management strategy, failure is likely to be worse. Obviously a pilot won't blindly seek failure to improve (I'll head for that mountain to see how well this baby handles crash landing). '...accidently...' - A lot can learnt (and mitigated against) from accidents.

I agree it's not black and white, but I think failure is more stark and thus sticks with us, helping us to grow.
