The post, "How can you be sure of your soul purpose or life purpose" below gives tons of information you ask above and we'd just end up repeating what's been given (shared). In honesty don't let something that's already been made available die on the vein. Be patient and it takes a lot of study and time imo in what's already there.
Anything specific your looking for that hasn't been said. That post has become kinda (too) lengthy and like a maze now to be sure.
but there's a lot of basic information there. again my opinion, if you dig into it and unearth what's there. I love gardening information to. Take what is useful and set what is not to the side. We can't start afresh but maybe a few repeats and we can get back to basics one line and crystallize here in one or two lines now. All's I can say is been there done that having felt it.
