Is there value to studying philosophy if you already know you want to do philosophy that has been done before?

I'm really interested in philosophy and I really want to pursue a degree in it. I want to be happy and I want to make a difference in the world. I want to use philosophy to make a difference in the world. <br><br>Revolutionary philosophy is very appealing to me. Marx and Lenin really changed the way I looked at the world. I like the idea of doing philosophy that pokes holes in established power structures. I've read a lot of philosophy in my free time. This is a big problem, I think. <br><br>I don't want to be original. I've read a lot of philosophy and I like it. I don't think I have anything new to say. I don't have any new insights. I don't have any new ways of thinking. I read philosophy because I love it. I don't have anything to contribute. I don't think I have a new philosophical thought in me that will change the world for the better. <br><br>I want to study philosophy because I love it. I want to use it to change the world. <br><br>There are so many people who are smarter, more insightful and wiser than me. I don't think I can say anything that hasn't been said before. Should I still go to university and study philosophy? I don't think I'll be able to change anything.
