You have now conquered your shiny Norwegian (Bokmål) golden owl. Yay!Now it's time to advance to the next tree level and probably discover more content and harder lessons with each level.
You are currently making 3.63 lessons per day on average and you still have to finish 339 sessions to get all of your skills to the Legendary Level, you would be there by 2022-09-30 if you keep practicing at your current pace.
Keep going! =)
