Blog post #4 (accordingly) Learning what the quote "I think, therefore I am" means vs what I thought it ment

When looking back at what I wrote before when trying interpret the quote "I think think, therefore I am" I was close when puting it in my words, but completely missed on my explanation. What the actual quote means is that everything you see,hear, touch, and imagin might not be real. But what is real is what you think about it. Your mind is the only thing proving your existance and not saying that your in a dream as when you dream, you can't really think, you just do whats going on. And what I wrote before is this, "But the one meaning that I (for some reason) think is most likely is that he knows he thinks for himself, so he exists." which is kind of correct because Descartes knows he is thinking so therefore he does exist.
