Counterpoint: You break your streak on a word you don't know. You get upset and look it up to see if it's even a real word. You discover that it means a Greek market, and start learning about that culture, maybe a little history.
Maybe you're pushed to learn other 5 letter words, to prevent yourself from losing your streak again. Maybe you start reading more because you want to expand your vocabulary.
All because you lost a precious game streak because you were pushed out of your comfort zone.
