Who can control our mood?

               Moods are influenced by so many factors. Climate, emotions as well as the surrounding around us can affect our moods. Well I know there would be many more. But these are the ones which I can guess of. I was never able to understand this concept and neither now. People say no one should have control over your mood except yourself. But I feel how much ever we try, it doesn't happen, isn't it? We care about what people think about us and feel about us. If the results are good, we become so much confident and are on cloud 9! But if the results are bad, our confidence dwindles and it comes back to square one. There is a Cold War then between your heart and brain.
                                  Inner peace begins the moment when external things stop affecting your mind, which is directly connected to your mood. So easy to say but yet so difficult to practice. I have come through situations wherein I cry because of some xyz reason or person and then laugh out loudly. 'Chuck dude' I say to myself. I feel that this must be happening with many people. But a truth that cannot be ignored is that these experiences definitely makes us strong. Being strong doesn't mean you cannot cry. It means how fast you confront yourself after crying and complaining. The mood automatically becomes good and normal. The more we look deep into this matter, the more complex it becomes. But during that period of time, just loosen your mind. Give time it's time. That can maybe recreate our smiles!
