You can use this website to shape your personality. But to really develop your personality, you have to use it. You can do that a little here by using the mail. The mail is also a good way to get help.
But sooner or later (probably sooner!) you are going to have to go to Second Life. Think of the shaping here as giving direction and guidance and your pesonality. Then the actions at Second Life solidify your personality. Anyway, it's fun to interact with people. And you like to meet people, right?
