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 individuals can learn from both but one can easily learn from losses because of the avoidance of such mistakes which become the cause of his failure. I think that getting a lesson from mistakes is better than leaving the way of success due to Losing of money so every single loss should consider as a lesson so one will not discourage because these mistakes sometime become a steps towards success.
the losses is not discouraging because there is no one who become millionaire at starting point but all those who have faces some difficulties and then cope up with these by using strategies become a successful trader and investors.
