Keeping these four principles in mind can bring on a sense of serenity and a new perspective in knowing that those off days are just that: off days. We all have them: the unexpected brings a twist to our routine, causing ripples and changing our plans. By focusing on positive thoughts, a newfound strength arises, and you will realize that this day too shall pass, and you will find the knowledge and courage to take on the situation.

It can be so tempting to want to gain payback for an action that we feel was unjustly done to us. However, you must remember how truly draining and useless this can be. Revenge assists a perpetual cycle of getting even: It passes from one person to another, but never really settles anything. And don't forget to take into consideration the effect it has on your emotions and mental outlook. If this is the only thing you are concentrating on, it leaves room for nothing else and drains you of all the positive energy you have to offer.

Although it can be discouraging not to have your hard work and efforts recognized at times, remember to focus on your performance and be proud of your accomplishments. Instead of feeling resentful, concentrate your energies and continue to apply a strong work ethic to your work.
