Happiness, true happiness, is an inner quality. It is a state of mind. If your mind is at peace, you are happy. If your mind is at peace, but you have nothing else, you can be happy. If you have everything the world can give - pleasure, possessions, power - but lack peace of mind, you can never be happy.
To complain is always nonacceptance of what is. It invariably carries an unconscious negative charge. When you complain, you make yourself into a victim. When you speak out, you are in your power. So change the situation by taking action or by speaking out if necessary or possible; leave the situation or accept it. All else is madness.
I write about the power of trying, because I want to be okay with failing. I write about generosity because I battle selfishness. I write about joy because I know sorrow. I write about faith because I almost lost mine, and I know what it is to be broken and in need of redemption. I write about gratitude because I am thankful - for all of it.
