How to Be Happy
So happiness - isn't that the thing that all of us strive to find and keep? Nobody is happy all of the time, but some people are definitely more fulfiledthan others. Studies on what makes people happy reveal that it doesn't have much to do with material goods or high achievement; it seems to whittle down to your outlook on life, and the quality of your relationships with the people around you.
only improving your attitude towards life will increase your happiness permanently.
Happy people aren't happy all the time. Everyone has times when they feel sad, happy, frustrated, guilty, and so on. Happy people are just better at bouncing back to a state of contentedness. We may all feel negative at some moment in our lives, but try to bounce back and live in the moment, and be content with everything you do.
Sometimes unhappiness can be caused by nutrition or sickness. Make sure you're getting all the essential vitamins and minerals and eating well.
