Can someone help me with this question on philosophy?

Hello,

I want to start thinking about philosophy and thinking critically and I was wonderin is it possible to learn philosophy by just finding out the major questions in philosophy, and thinking and writing about them from my own perspective and having conversations with others about them and finding out their opinion of things, or would it be better to buy a book on philosophy. It seems like to me just finding out the questions of philosophy and thinking and talking about them with other people is alot better than buying a book because conversation is what philosophy seems to be all about, but I wanted some other opinions. Thanks in advance.
