Thank you guy, I watch this link.

In my opinion, for the beginners, remembering them with particles would be better because "I, my, me, mine" all have "watashi" in their translations. So, "I" = watashi wa / watashi ga, with "ha" or "ga". I think these two particles will confuse you but please get accustomed to them little by little. (Please take a look at this, http://www.italki.com/discussion/86044) Good luck!
