Life is not always what we want but it can be changed to what we like.
Sometimes your attempt may be fulfilled or some times it may be missed.
But if you can satisfy with what you get and what you have then your life will be simple.
With my experiences I know that Life is Happiness.We do all these things to have a happy life.Eating,Studying,Loving and even Dreaming ,we do to gain that happiness.So if we can't enjoy the life then better to change that life rhythm.But never even think to restart you life according to your moods and feelings.Give priority to your knowledge.
