Experiencing Happiness

Happiness is an abstract word which has got a vast meaning in everyone's life.Happiness can be defined as situation when one is comfortable or feeling cool.Happiness is the something desired by all.But to get happiness,it is not that simple.And also the condition of happiness depends upon person.
Actually what happiness is?Is there anyone who can explain this.I guess its none.Because for instance  the thing that makes you happy can not make the other person happy as well.For a poor family,to get food,shelter and cloth easily in their life is the biggest happiness.But for the rich family its nothing except day to day activity.Similarly,for a brilliant student passing in exam is nothing but for an average student it means alot.Likewise,for scientist discovering new things is what happiness is but for average people that thing is the toughest.
To experience happiness in life one has to go through series of phase.One can't easily pursue happiness.Like for an employ working in company,his happiness is doing his job properly.But to accomplish his work,he has to go through many problems in his office.After facing many difficulties he get one time to feel that happiness.Similary,for scientist true happiness comes when they succeed in discovering new thing.But to discover that new thing, he goes through hell.
Happiness is always good for health.It is neccessary for everyone to be happy.But happiness can't last forever.So,its up to a person to decide how to be happy.For me key to happiness is positive thoughts.The more positive i become,the happier I am.If I take everything in positive way then there is nothing that can make me feel unhappy.Try to be happy even when you are in greatest trouble.For Mahatma Gandhi happiness was simple living.So,be happy and always live your life like you going to die tomorrow.
