Happiness and freedom begin with a clear understanding of one principle: Some things are within our control, and somethings are not. It is only after you have faced up to this fundamental rule and learned to distinguish between what you can and can't control that inner tranquility and outer effectiveness become possible.
Within our control are our own opinions, aspirations, desires, and the things that repel us. These areas are quite rightly our concern, because they are directly sunject to our influence. We always have a choice about the contents and character of our inner lives.
Outside our control, however, are such things as what kind of body we have, whether we're born into wealth or strike it rich, how we are rehared by others, and our status in society. We must remember that those things are externals and are therefore not our concern. Trying to control or to change what we can't only results in torment.
Remember: The things within our power are naturally at our disposal, free from any restraint or hindrance; but those things outside our power are weak, dependent, or determined by the whims and actions of others.
Remember, too, that if you think that you have frre rein over things that are naturally beyond your control, or if you attempt to adopt the affairs of others as your own, your pursuits will be thwarted and you will become a frustrated, anxious, and fault-finding person.
keep your attention focused entirely on what is truly your own concern, and be clear that what belongs to others is their business and none of yours. If you do this, you will be imperious to coercion and no one can ever hold you back. You will be truly free and effective, for your efforts will be put to good use and won't be foolishly squandered finding fault with or opposing others.
In knowing and attending to what actually concerns you, you cannot be made to do anything against your will; others can't hurt you, you don't incur enemies or suffer harm.
If you aim to live by such principles, remember that it won't be easy: you must give up some things entirely, and postpone others for now, if you want to assure the attainment of happiness and freedom.
