Do you think the feeling that you should do something comes from within or without? Are those things your true purpose?

I think it comes from within. Your true self is inside you and it is usually correct in letting you know if you should do something. But even that needs help sometimes, and it doesn’t hurt to get some outside advice before deciding to do something. As for it being your true purpose, you have to look within. Does it feel right? Did it fulfill your mind, body, and soul? If so, then maybe that is your purpose.
