Complain or Change.

Although I know that complaining is not a good idea, but how can I stop it from reality? Does it make me feel better? Yes, it does. But I know and read so many quotes that says complaining equals to losing, so it is the best for me if I can just change and do better. Imagine, if I keep everything to myself, then I might explode... Really, I do need to change because I want to succeed, and I guess complaining is the obstacle that kept me from winning.
