Learning from others
Every man I know is better than me in some sense. For that reason, I learn from him.
We can learn something good from any human being, but you must be willing to appreciate it.
And for that it is essential to put into practice the virtue of humbleness, which is nothing more than an attitude of openness, the acknowledge of what we do not know far outweighs what we know.
Pride and arrogance encase us in ourselves and a mind that feeds itself only ends up becoming impoverished.
Anyone has a lot to add in some part of their life. If we are humble enough to approach their wisdom and allow it to express it, we will have an opportunity to continue to grow.
