i'm thinking therefore i am existing

It was Rene Descartes, and "I think, therefore I am." Actually, it was "Cogito, ergo sum" in Latin. In my opinion, he should have stopped there, because many things he was "certain" of after that were not built on a solid foundation of skepticism but rather clouds in the sky.

GOD has a plan for everyone of us, it might not be now, but sometime, you'll see what GOD has done for you.

The one who said that dictum was the philosopher and mathematician named Rene Descartes. I learned it from my philosophy class. First, Descartes was searching for a method to attain certitude because in his time it was a cloud of doubt. People are not sure whether there is certitude or not, whether can man know or not. He doubted everything and even the senses because sometimes our senses deceive us. Even the method of mathematics as a science has put into doubt. He doubted all things and in the end there is one thing that he cannot doubt of. He cannot doubt that he doubts. In this case, the first certitude is that there is an "I" that thinks. I think therefore I exist. From then on, people have already the certitude which is the existence of the self or ego. In this way, Descartes was considered as the father of modern philosophy because he builds a strong foundation of science and enlightenment. Later, some philosophers call the self as the spirit or reason. It follows that the age of reason arises and it culminated in Immanuel Kant. I am glad about your plans in life and I hope you will be able to do so.
