An easy way to start is to unburden yourself of things you no longer need. That can be as big an idea as cleaning out a storage space or garage or simply cleaning out your purse or the glove compartment of your car. Space in itself is a gift you can give yourself no matter how small a space you live in. You could actually live in a huge house but have a cluttered night stand or bathroom sink that makes your life a hassle everyday! Clear those spaces and feel the joy of a place to set a cup of tea or a book you're reading, or a candle.
If you need an emotional clean out, try going through your boxes of pictures. You don't have to save every picture of everyone you've ever known. You may find pictures of people you no longer associate with. Why do you need their picture? You were there anyway. Who needs the picture?
Isn't it time to stop beating up on yourself about your weight? Often, once we accept who we are a healthier self will follow. How about your age? Perhaps throwing out clothing that you probably won't fit into again and may be too youngish a style, ( belly shirts,) are something you should let go of. Give yourself a break! Buy something that looks great on you that you can wear today.
Then there's your health. How about a good look into your freezer. Throw out the mystery food and eat something fresh. You deserve it!
Now let go of your limitations! Enter your painting in an art show, go dancing, join a book group, sing Karaoke, whatever! Add something valuable to your life. You won't regret it.
