No one has a perfect life, we all make mistakes now and then, so STOP belittling yourself when something goes awry. Change your negative thinking to positive thinking and you will not have to worry about what can go wrong, but only think of what is going right. Live in the moment so that you can enjoy your life and not sit worrying about what is going to happen next. So many people waste their lives worrying about what is going to go wrong or will I get the job, or will I ever get married, will anyone ever love me. These thoughts only bring what you don't want, if you want to be loved, love yourself first. The more you show yourself love the better your life will be. If you cannot love yourself, how can you expect anyone else to love you. You should always come first in your life, even if you have children, remember what they say on flights 'put your mask on before helping your child'. If you cannot breathe, how can you help anyone else. You must keep this in mind.
Today change your thoughts to that of Love and acceptance of who you are.
