End of the World Part III

I have always believed in hard work, if I wanted something I am willing to give it my all. So today as I write this post I am once again frustrated. I work a full time job that I truly love and believe that I make a difference. I am always seeking out new opportunities to expand my mind and my bank account. I take every opportunity and give it everything that I have. For example, writing these daily posts, I enjoying writing and I hope others enjoy reading my posts. But I know that we only use part of our brains and I want to use more of mine. So I wonder where does one go to find more out of the box opportunities? How does one sift thru all the bullsh#@ that's out there? Does any other human being even want to share what they know so that others can expand and gain from their knowledge? Or is the vast public at large just considered about themselves? See this is what I do not understand. We were put on this planet for a purpose and I refuse to believe that we were meant to be selfish, self-centered individuals. Maybe someone here can enlighten me. I would love to hear from you.
