"飛べないなら走りなさい、走れないなら歩きなさい、歩けないなら這いなさい、でも何をしても前に進み続けなければなりません。"

Simplified Meaning:

When you face challenges, you should always keep trying, no matter how hard things get. Sometimes, you can make big progress quickly, like flying. Other times, you might only be able to make smaller progress, like walking or even crawling. The important thing is to never give up and always keep going forward. Imagine you want to learn a new skill, like playing the piano. Some days you learn a lot and feel like you’re 'flying.' Other days, learning seems harder, so you may just 'walk' or 'crawl' by practicing simple notes. Even on the hardest days, doing something small is better than doing nothing. This idea teaches us to keep improving ourselves, even if progress is slow. Everyone moves at their own pace, and every little step counts towards achieving our goals. So, whenever you feel stuck, just remember to keep moving, no matter how small the step.
