You're missing the point of Skyrim.
Not quite, I've been trying my best to take it slow, roleplaying and keeping to what my character would do, yet I find some parts of the game being far too short. For example the mages guild, one person mentioned urgency, that's one reason it felt very short to me. In an RPG if there is a sense of urgency to a quest my character won't suddenly forget about it, no it will be a very high priority for my character. That's what Oblivion did better, it had a ton of quests with little urgency to them to start with while they still had their own story and flavor. And at the end when you had done the quests in every town you got to the main line of quests at the arcane university which had a small epic quest line that had urgency and importance to it.
In Skyrim it's like they skip making you do all the prerequisite quests and just throw you into the arcane university and the main storyline still manages to be shorter than it would be if you were just thrown into the arcane university at the start of Oblivion.
And there is no sense of rising through the ranks at all (heck, there are no ranks...), Oblivion was already doing this pretty hastily with some towns like the quest in Anvil where...
you get thrown into a high risk situation to your very being against a murderous battlemage even if you just joined the guild
... and in Morrowind this was done even better where most would start out doing the quests for Ajira getting her alchemy ingredients from the wild and helping her with her rivalry against Galbedir, and then you get to have your hand at more dangerous tasks.
In short the pacing in Skyrim is all wrong.
