Doing what you like, listening to warm music, going out for fun and seeing the scenery of life is also a happy way. Go out for a walk with friends and exchange heart-to-heart friendship. People, once they are free, will think a lot of things and make their thoughts complicated. So, get busy and live a simple life.
Life can't be sunny forever, with ups and downs, troubles and loneliness, and life is colorful.
People can't be happy all their lives. Forget troubles, sadness, pain and frustration, yesterday, myself and fragile feelings.
So don't worry too much. Let's go I wish you a happy life, happiness (* _ *) ...
