Don't fast travel.
You miss funny encounters, herbs, treasure, side quests, more herbs, and it adds to the experience.
I personally prefer to act as if I am my character, I search everything as much as possible, take things slow, read books, practice magicka at the College of Winterhold, to small quests and never fast travel.
All of this makes you feel as if you are there, and for your obsessive Skyrim, that is what it is all about, playtime and the feeling of being there.
Of course, if you are, like a very high community, someone who does the main quest and then say they have completed the game at 30 hours, when they have missed out 470 hours, then don't.
