You need to feed your mind as well as your body. READ. LEARN. DO.
Life is short. What are you waiting for? Take that trip you have always dreamed of. Start your own business. Use the good china. Take chances. Quit making excuses.
The only things stopping you are in your own mind. It's not too late to be the woman you've always dreamed of being. What have you got to lose? Try.
