I have done Duolingo for 300 days straight now, and I feel really great!
See you at 400 days!
Gut gemacht! Good job! Buon lavoro! Buen trabajo! Bon travail! Bom trabalho! Отличная работа! (I totally just tried to write 'good job' in all of the languages you are learning, though I think English is just the reverse tree, right?)
Great job? Is your country's flag yellow-blue-red?
(no, I'm not colombian even though my user photo might look it)
