People have mouths and aside eating, the next thing it does is to talk, so why live your life based on what people say? Most people fall into depression or worst of all suicide because of criticism. You succeed, they say you have pride and when if you're poor, they call you a failure. It does not matter what you do in life, you can not please everyone.
Aiming to please everyone is pleasing no-one, so why not do things that make you happy? You do not have to react to every criticism. Most people who criticize do not truly have the perfect life they portray. They know you are better at what you do and they feel really bad about it but the only thing they can do to make you feel inferior is to criticize what you do because they know they can never measure up to your level so they try to talk you down.
They say you are fat, so you cut down your calories and start a weight loss plan but they say you will end up dying of starvation and when you get the target weight you think they want, they say you are skinny. Go on that date because you want to, start that weight loss plan because you want to be slim not because someone says he/ she prefers you to be slim. Do what you want not because they say it is good but because you know it is the best for you.
