The approval of others, when it exists at all, is fickle and fleeting, always leaving one to worry how long it will last. You can’t be responsible for the world; you can only be responsible for yourself.
True happiness is dependent on others.
In all lesser things, we must choose our own destiny, but those things that matter most (i.e. love, approval, acceptance, understanding) can only come from others and must by their very nature be given freely. It cannot be forced, or else it will never satisfy. It cannot be earned, since the others will not tell you their standards, they do not even know their standards, and their standards are inconsistent.
This is why I'm grumpy.
