Sometimes, you have to stop listening to what other people think. If you know what is right for you, then it really doesn't matter what they think anyway. They aren't you. Stop using them as an excuse. Stop allowing them to let fear in. Stop letting the doubt creep in because of them. Stop blaming them. Stop holding back.
Be confident in your choices and your abilities. Trust in yourself. Don't let anyone hold you back from doing anything you know you should do. Go after what you want and need, no matter how scary it seems. You deserve more (and better) than anyone else thinks. Take control of your life and get to work doing what you want to do.
