First you have to like yourself, forgive yourself about the past mistakes you made. Make out time for yourself, and during such time take a close at the mistakes you made and how well you have improved on them. Make out time to pamper yourself and be in a relaxed mood. Listen to positive and soul lifting messages and music. Look at the positive side of life, and surround yourself with positive people who can help along your journey. Happiness is a thing of the mind, so work on your mindset, be happy with others and learn to share your thoughts with others too.
