A friend of mine used to say me quite frequently that if you can't see the brighter side of life, then try polishing the dull side. This statement was pretty strange to me, as I couldn't possibly judge which side was brighter and which duller. It possibly happens with most of us, and at many times. We find ourselves so clinched with some problem or the other that we start getting a feel that we're the only ones who face all these problems.
We probably see, or sometimes even ignore the other side of the coin. We are at times immersed within our own cubes that looking towards the sunshine at the other end is way beyond our reach. Some lips even speak about the out-of-the-box-thinking thing. Endowment of knowledge or the skill to solve problems might have been there, but ignorance of the same might deprive us, of what we have.
That's exactly where optimism brings multiple spaces for everyone. It brings with itself multiple rays of hope, and with hope, comes the will to strive for things, which probably might be beyond our reach. An attribute, so simple and so elegant, tries to polish the dull side, with it's own beauty.
And as some one had said, positive pictures come out from the negatives developed in a darkroom. So, if you find yourself lonely and in dark, understand that, life is working on a beautiful picture for you.
