Do what makes you feel happy and fulfilled. No one is better able to take care of you than you. Look for the positive side of life's events. Negative thinking is self-defeating. Tune into your thought patterns and when you find yourself thinking negatively, stop and consciously change it to a positive thought.
Positive people are fun to be around.
Take time out regularly to be alone with your thoughts and feelings. Get in touch with your life. Stop to smell the flowers and listen to the birds. Improving self-esteem means taking a close look at yourself, appreciating what is helpful and changing the things you are not satisfied with. It may not be easy, but it can be tremendously rewarding.
