I can agree with you that mankind has gone down the materialistic path and finds emptiness at the end of the road.
Now, my dear friend, you cannot change the world BUT you can change yourself, so begin by deciding what it is you want in life, study your strengths and weaknesses, your skills, and see where you'd fit into the scheme of things. We all have an important role to play and we ought to make a valued contribution to our world if and when we have the opportunity to do so.
As for living the party life, that's just the bright lights, sights and sounds and smells that are bombarding your senses as well as your brain, and you think it's a good time. Don't forget, Saturday night partying is usually followed by Monday morning's back to reality real world.
I would suggest you start to develop your inner world, find out what really captures your interest, read books, learn about artwork or music or writing. Join groups to share similar interests, get involved because there is so much to be experienced that has fine value in developing you as a bright, mature human being.
