If you took one-tenth the energy you put into complaining and applied it to solving the problem, you'd be surprised by how well things can work out... Complaining does not work as a strategy. We all have finite time and energy. Any time we spend whining is unlikely to help us achieve our goals. And it won't make us happier.
