One thing about animation and probably all other skills is that it is a never-ending learning process. So gotta always 'Stay Humble & tolerant in accepting criticism & feedback'.

This is definitely part and parcel of life, it its entire essence itself! Regardless of occupations and life backgrounds, we are on this journey of learning and un-learning. :D It is interesting to know that physics is also required for animators, thanks for sharing, @zord189! :)
