Resist seeking happiness from the outside in. Instead, focus on gratitude practicing gestures that bring happiness from the inside out. If you allow your self-image to be at the mercy of unpredictable events and unreliable people your happiness will be forever on a roller coaster ride! Your happiness must always be an inside joy! Your happiness cannot be dependent on someone else. You own your happiness.
Try not to focus on all the ways the world has done you wrong, instead count your blessings one by one every day! If necessary make a list daily of 5 things you are thankful for. This is a great exercise to do at the end of the day, give thanks and appreciate for all the blessing you have been allowed to experience. Cheers!
