Hating your life is definitely the most awful thing you can do: such hate then immediately becomes a self-fulfilling prophecy, since Source will always give you more of what you focus on. Fortunately any tendency downwards can be transformed into an upwards direction, even if at first the effect seems minimal.
Love or even Lust for Life will bring you more life, and focus upon the ability to help will not only bring you more situations where you can help, but also more situations where you are helped instead. This is not a world of tit for tat, but a primary law of love: the more you give it, the more it is returned.
