Being humble is completely different from being scared, the squirrel seems to be scared but humble. Naturally squirrels don't stay calmly and discreetly, in fact they seem to be one of the most rascally rodents species with their distance cousins Rats and Mice.
Regardless of your energy and zeal like the Squirrel, be humble and respective to people and anyone that comes your way. This is a basic courtesy, but the World is a strange place hence people can't be predicted with their behavior and reasoning which could be fatal to people around them or themselves.
2020 marks the beginning of a new decade, it cost nothing to remain humble irrespective of how much you make, how rich and wealthy or brilliant you are. Pomposity could cause more damage than good, not being able to remain under leash. Just this new year some, guys spent millions on booze at a club and they were busy boasting about how much they make per day, shouting at the top of their voices. I hoped they all got home safely and not robbed or mugged.
Humility is a great virtue everyone needs to go far ahead in this life, you need it this new year and the next, and the next one and beyond. Keep it simple and on a low key, peace be with you all!
