I've never understood why children are taught that it's okay to lose as long as you tried your best. It is not okay to lose. If you tried your best and came up short, you're a loser. That's literally the definition.
I'll play games of league and freaking rage on my team when we're losing. At that point I would literally rather be doing anything else but playing that game because there is no part of losing that I enjoy, or appreciate, or want to be part of. So why exactly do we teach people that it's okay to be a loser? And what's the point of having a good attitude about it? What exactly do you gain from not caring about the outcome of something you're supposedly trying to win at?
