In my opinion, I believe that there can be hundreds of books authors can write about the negative ramification of sarcasm on anybody. So what to do with it? It starts with recognizing that sarcasm is a habit. The good news is, since sarcasm is a habit, this means just like any habit, it can also be crewed.
Try fasting for one week without using sarcasm. Maybe even for just one day and see how you feel, or better yet, look at the reaction of others, and take good note of how they feel after they speak with you.
Side notes: The opposite of sarcasm - honesty! Mental Tools: equate honesty with friendly, encouraging, proactive in relationships, and encompassing character. Good luck!
