For me happiness are little things like rain make me so happy and little appreciation from my elders or a compliment, a little gift, reading my favorite novel, watching favorite anime, helping someone in their hours of need and then seeing smile on their faces, giving surprises to my dearest, they all make me feel very happy.
I don't demand big things or big happiness but a little little happiness, which are a part of everyday life, which don't let you go out of track, which light your mood every now and then, which make you a better person for me all these are source of happiness.
A phone call from my bestfriend is also make me happy and having my favorite food for dinner, a get togather with family and friends makes me so happy however it doesn't mean that a get togather should be at a big classy place with all the eating stuff and glittering dresses but if you are with your family or friends in a small place or in a room and having fun there then that would be enough to provide you, your desired happiness. Remember happiness does not require materialism or effort on a larger scale, even a little effort of someone for you makes you happy that the other person thinks about you, care about you.
Every person has their own perception about happiness, we can't compare one from another but the goal would be same that leads every person to the same point no matter what street they chose i.e. "happiness". A real happiness is the happiness which you felt from your heart and soul which fills your heart with joy and stomach with flying butterflies that is the real happiness, always seek for that kind of happiness.
