All good consists of some bad. And all bad consists of some good. (Good and bad are relative concepts afterall.)
Yes, wanting something to be perfect (without negative consequences) is a sign of wanting to better yourself – but truly believing that perfection is attainable is a sign of delusion.
The invention of the ship was also the invention of the shipwreck.
But that does not mean we stop crossing the oceans because shipwrecks are now a probability. No, it means we must take the good with the bad. It means that we must calculate and see whether more good than bad is created, and if it is – we must continue.
We don’t stop walking for fear of falling. So why should we stop trying for fear of failing?
