Today’s Tip of the Day: Be aware of people’s ignorance and make yourself better because of it. Know that some people just lack proper mannerism, are oblivious to things, or are just all-around assholes.
This is not to say that you should act like they are or judge them as bad people. I am just saying, to be aware that some people were just brought up different and they will act in ways that catch you off guard. My advice is to recognize other people’s faults and indirectly try to help them with them and to also learn how to avoid acting the way they act, when you do not like it.
