uhm... u can spend all your time to stay hidden BUT it ll be never enough, because who "know" how to work in the net s A LOT more skilled than you.
expecially if u live somewhere where a government is pushing to control the nation.
another problem is... yourself. "more you speak" and more you are trackable. maybe u say about a place that few know, a fact, or someone... and then it s just a matter of time to know who is who.
or maybe you expose yourself by error (like... put online an image with gps location set on, or just reply by email using by mistake your real name...)
in the past i followed some anonymous who paid the price of this kind of mistakes. and some of them was not "newbies".
so... as many time is said... up to you.
if u want, do it. but stay also ready to "something".
