When you don't know how to do something or don't have any ideas, look what did other people before you and how they did it. Everything you want to do was done by someone else before. Go and get inspired from them. It will help you to find your own way.
It's never too late to learn new skills.
Remember. You are your best friend. Don't be afraid to be honest with yourself and admit things.
Even if you don't feel the best today, smile at yourself in the mirror, smile at your husband, kids, smile at the bus driver or saleswoman in the grocery store. They will smile back and you will suddenly feel better.
