While i was walking to get my car at the office's car park, i saw a big rainbow across the sky. Out of the suddenly my mood swing from feeling tired to excited and happy. I felt like i was filled with hopes and motivation. Dunno why but i just like the rainbow. Maybe because to me, it symbolize that all the difficulty time will pass and the light of hope will come at the end.
Happy or sad is just a thought in your mind. We can be happy if we tell our mind that we want to..... and vice versa :)
