First: Make yourself happy

The most important key to your personal happiness is determining that you will be happy. For many people, their personal happiness is not a priority in their life. Too often, we put the happiness of others before our own. While this may please our children, spouse, or boss, this is not the path to happiness. This dos not mean you should make yourself happy at the expense of others, but you must remember that the reverse should also not be true -- your happiness should not be sacrificed to make others happy. Once you have determined to make your pursuit of happiness a priority you need to determine just what it is that makes you happy. Spend some time reviewing the happy times in your life. Think about memories that make you smile or activities that make you joyful. Can you find a common element or theme? Then that is one of the keys to finding true happiness for you. [Source]
