Happiness is not a state to arrive at, but a manner of travelling
Everyone of us has a tendency to become sad and feeling lonesome without any reason or possibly were just downhearted. We can't deny the fact that one day in our life we become very angry to a point that we lose our control and resulted to a negative situation and confrontation. I don't know, but what I do believe it's normal on one way or another simply because this is just a way for us to express our deep feeling of hatedness. But beyond that when you see yourself that your doing these almost everyday and you felt that people become aloof and snooty about you Ei! you have a big problem!
I find these quote a bit revealing and enlightening to an extent that it opens a lot of thought on my mind that hey! I think this is true, it's really true that for you to be happy you need to take each passing minute of your day with smiling face. Not trying hard to give a smile to everyone but rather you savor the time that pass by each day. In that way you will find that happiness really rely on yourself. It's a state of mind and it's a choice of being happy.
