I was born Catholic, changed to Islam, so yes, I am thinking for myself. I do not narrow my vision to one thing, as I read legitimate books (not online articles) on Buddhism, Hinduism, Zoroastrianism, Taoism, Judaism, of course Science and technology, and many philosophical and political doctrines. Based the information I learn, i create my own conclusions. So, in that case, I think I am doing as you would like :D

Well it just so happens that the Quran actually encourages deep thinking, it tells to reflect on the world around us. It doesn't just tell us to accept but tells us to ponder first. I didn't decide that I wanted to become a Muslim in one day, after a while I decided it was right for me. If being atheist is right for you then more power to you.
