Don't be too quick to deny someone else equality and fairness. You may have worked hard to get where you are, and to attain what you have, but that doesn't mean that other people aren't entitled to do the same. If we deny others the very things that we fought so hard to get, we begin to behave like the people who tried to hold us back and put us down while we were climbing up the ladder of life. Sometimes you'll overtake someone else, and sometimes they'll overtake you. What matters is that you don't become the sort of person that always chooses personal gain over equality and fairness.
Bad bosses often say bad things. Don't take them personally.
