I don't believe, "You Learn More from Losses than from Wins" because that's incorrect. One can learn both ways. In fact, I learnt more from my wins than I did from losses. You talked about losses like anyone wants to have them and then readjust from such. If there's anything losses will even do to beginners, it's to scare and discourage while introducing them to reality.
Yes very correct, you can learn from losses and can also learn from your wins all still form part of experience, so we can say we learn from our past experience weather win or loss, but I think the one that makes us more carefulis the losses because you won't want to loose either your money or whatever resources that was invested in it.
