It took me 10 hours or so to get a hang of it and enjoy it to it's fullest. Then I started to understand leveling perfect and the game became boring because every second I dedicated to leveling effiecently.. then I stoped doing that and not caring... so now everything is very much fun

So my advice is to hang in there for a lil while until you grasp menues, understand that you just need to explore a lil and go in to your first dungeons and ignore the questlog/take it when you feel like it.
Myself on the second char that is my "main" I havn't touched any quests yet... you take a few steps explore and then do whatever you feel like in that specific moment hard to describe what the game really is about.. I like to think of it as George Costanza..
" it is a show game about nothing" ... Just go out there and do / explore what you feel like... the world seems so huge it will take you a while to run out of things to explore, guilds to join and quest with etc and the best part is.. do it with the char you feel like, the time you feel like doing it etc etc.
