Young man, the secret of my success is that at an early age I discovered I was not God. --Oliver Wendell Holmes
Sometimes, in our families, we try to get parents or brothers or sisters to treat us the way we want them to, to do things we want them to. When they're upset or angry with us, we try to get them to stop, rather than allow them to be angry.
But our feelings are ours alone, and we are responsible only for how we feel. Those around us are not the cause of our feelings. We are.
This knowledge is a big responsibility, because we know we cannot blame others for our bad moods. But it is a fact. And this fact is also a wonderful freedom for us, for it means that we also have the power to make ourselves happy, no matter what goes on around us.
