Will there be any problems as far as astral projection goes, if I was practice all day?

I'm basically done as far as living my physical life and I'm going to just raise my energy hours upon hours. I just want to make sure that there won't be any problems (Not lifestyle problems) if I was to do such a thing.

I have no job and about to go to school...but thinking about not even going to school because at this point its going to be a waste of money. If anything I will get a little job just to pay a few bills in the house and spend the rest just doing this.

Also is it possible to have session talks with spirit guides because I really need to talk to them.
