The purpose of life isn’t clearly defined. That’s up to you, if being happy is a goal you want then go for it. My purpose in life is just to sustain my existence. That’s it. I work so I can pay to live and eat. And in my free time I do hobbies and things I like to entertain myself. Am I happy? I dunno, but I’m still here. That’s the best I can do. This life is all we have so might as well keep it going as long as you can.
