There isn't a single person in the world who is right 100% of the time.
Literal zero.
At the same time...
There's no shortage of people with egos big enough to think they are.
A lot of these people will even ride their egos all the way to the bottom without awareness of it until their entire life is a dumpster fire.
Don't let that be you.
Develop the skill of detaching yourself from your beliefs and allowing yourself the opportunity to learn and adopt new perspectives.
Part of living a happy and fulfilling life is being able to admit when you're wrong...
...and changing your mind when it's appropriate.
There is the truth and only the truth.
Never let your ego stand in the way of it.
You'll destroy your life if you do.
