Yes, you learn from losses. But you shouldn't celebrate losses as if they are moral victories. That's not the mindset that is going to propel you to the highest levels of success. True winners hate losing of any kind. You can't just console yourself with the "I did my best" mantra. That is a cop out. It's about going for the W: Every. Single. Time.
What's wrong with the world today? Like you, I get on the internet & social media & think, "WTF?" Like...it literally seems like society has become an insane asylum & the lunatics are running the place. Everybody is angry & resentful at everybody else. Well I heard a great story that provides a two word answer for what's wrong with the world. If we take that answer seriously, we'll all go a long way in fixing society...and our own lives.
