You can glide through life like a duck or you can knock everything down like a Bull. Both will be a different kind of life and both are sometimes necessary but neither is a great way to be all the time. The most advanced people can use both types of behavior when necessary. They allow the small things to go over their back while being able to step up to the bigger issues.
The duck knows that the issue is there but lets the small things slide because getting caught into other peoples issues and behaviors has no advantage. It is best to navigate around these issues and keep going so that they can have peace of mind and accomplish their goals.
The bull will charge and fight with every slight. There are times when it is best to not let issue go and stand up for them. To fight is very noble but only when you are actually being noble and it has some purpose. If it is all about ego then it has little to no meaning and you will simply look confrontational.
Knowing when to be the duck and the bull is important. Small issues should not bother us. Most of the time it is unintentional and not worth our time. There are times when such behavior is repeated and needs to addressed. That doesn't mean to fight such issues but to address them with strength and courage.
