If you do these four things, you'll be happier:
Think in Terms of Long-Term Happiness
A lot of people confuse bursts of short-term excitement or elation with a long-term pattern of authentic happiness. There are many things that will make you happy for a short while but what will bring you joy in the long-term is the deeper more meaningful things in life like loving yourself, meaningful relationships or a fulfilling career; behaviors that require a lifelong commitment.
Not everything in life is a matter of life or death. If you live that way, you'll always be on heightened alert and it will take a toll on how happy you feel. Try looking at the lighter side of life as often as possible: Laugh about things, say silly stuff, smile often, hang out with fun friends or tell some jokes. You'll be glad you did because life won't feel as serious or heavy.
Each Day is a New Day
No matter how yesterday went, or the previous part of your life, each new day offers the opportunity to move in any direction you wish. Wake up and take advantage of this wonderful chance to do whatever you want. You can follow your passions and start living a happy life whenever you decide you want to do it.
When you live mindfully you move from thinking and doing things unconsciously to behaving carefully and deliberately. Most people cope with the events and people in their lives by reacting the way they always have rather than by doing some planning beforehand. The key to being truly happy in life is to take that extra moment before you act to rethink what you're doing and move in a positive direction.
