When figuring out what you want for your body, how you want to look, make sure you write down the best that you want. Don't just write down I want a better nose. That's too small. The universe can give you ANYTHING you want so why ask for the smallest things. Ask to be extremely gorgeous, supremely attractive.
Next, once you wrote down what you want, go and work on it. Dress well, eat healthy, workout or exercise or go running, etc...You must take action because action is the key to changing beliefs. You'll start believing you are extremely gorgeous.
Then, you'll manifest. Happy manifesting guys!
