In life you have to do what makes you happy. You can’t live your life overly concerned about someone else. There will ALWAYS be naysayers that think you should do this or that, but if it makes you happy GO FOR IT!
You do your best when you are happy. Happiness is the best motivation.
Happiness is contagious (I strongly believe this). MOST of the time if you are happy or positive it transfers to the people that are around you. Who watching you? How are reflecting your happiness?
