Being happy is relative, wanting more doesn't mean not being happy…then it also fluctuate everyday, through the day and night.
I am happy, I am content, I work toward better every moment, day, week, month, year.
Buddha realized that people were miserable or unhappy because of the desires of their heart being so important and a condition of their happiness. Be happy, love yourself, enjoy every single good thing, person, moment in your journey and keep on moving forward.
Love and peace to all.
