Everybody who calls someone a tryhard is just redirecting frustration over his own failure towards those who can accomplish more with the same effort.
Also, the names that go down in history all almost exclusively tryhards. Einstein tried hard, he became the patron saint of intellectualism. Bill Gates tried hard, he became a billionaire. Jimi Hendrix tried hard, he became one of the greatest guitar players of all time. Dschingis Khan tried hard, he became emperor over the largest empire in the history of the world. Fatal1ty tried hard, he is still paying rent from gaming dollars. I tried hard, I won games and got into gold where life is good.
