You should be completely uninterested in believing in anything that doesn't put you in a more positive state. Shout all day about this and that thing bad, but what do you actually gain from it? All you're left with is a shittier mood as life continues to pass you by You don't need to hate stuff to feel important. Doesn't make you look hard either. Generate your sense of purpose through thoughts that will actually make your life better. Only so much time and energy before your plug is pulled. Have to choose wisely
