If you had to give up one word that you use regularly, what would it be?
Words has and carry a lot weight on how and in which situations you desire to use them, If I have to give a word would be giving up part of my own personality that has root cause of what I am or what you are.
In general you really need such words to express your innate intention wether that be good or a bad one.
Would I give up all the negative words? probably not, but can I be a better person and improve myself to be courteous and not make fool out myself, then yeah.
Bottom line, might be cheesy, Be Yourself and with experience that might hold or progress you, is a good sign you might be doing something right.
