Put down that peyote and realize that you are a human so where do you get off saying "you humans". Go read Ecclesiastes and know that every human accomplishment is meaningless in the grand scheme of things and every pleasure you seek is also meaningless. Seek god if you want to be happy. Solomon is the man who wrote Ecclesiastes and he tried to find fulfilment in every sensual pleasure, every field of learning and owning every possible possession available to him. None of that gave him true happiness. Only those who know and fear the lord will attain true happiness and fulfilment in their life.
Only the fearful and diffident shall be happy and fulfilled? Oh tell us more doubleplus good speak.
The point you missed is that the acquisition of "things" or seeking to experience all manners of "sensual" pleasure do not result in longterm fulfilment or happiness. Solomon had more gold that any of us will ever have. He could buy what he wanted any time that he wanted. Fear is this case would be awe,reverence or respect for the power of god. That is much different than living in paralyzing "fear". Some fear can be healthy as it helps you stay out of trouble. When you look at something like the Niagara falls in person, does it give you terror or does it cause a sense of awe? Does that feeling give you a positive sense of euphoria? Now imagine a god who created all of that awe inspiring power, other inspiring phenomenon and the universe itself. Now consider such a being caring about you personally. Wild, if you actually think about it even as a thought experiment.
I can somewhat relate to Solomon. I used to be into acquiring things and travelling around the world experiencing new things but I found that none of that ever really gave me lasting joy.
