Thanks for your comment and words of appreciation! From this year onwards, I am focussing on building habits rather than chasing goals. It's relatively easy to develop habits than to achieve goals. Every day, during lunch break in my office, after finishing my lunch in 10-15minutes, I devote 15-20 minutes to German Lessons in DuoLingo.
My strike has nothing fascinating as compared to those who have kept it for 3500+ days strike. Imagine someone learning it so consistently for the last 10 years without missing a single day! There I get the motivation.
