I steered off from the main quest to other stuff. I started to word wall hunt, dragon hunt, kick Stormcloak ass with the Legion, misc objectives, and sidequests. Every now and then wen I have no quests or jobs to do I will do a mission in the main quest until I find something else to do. On the "Diplomatic" quest in the main story..
I'd say that killing the Whiterun Dragon and then putting of doing 'The Way of the Voice' is a good compromise.
That's what i'm doing with my character. I figure that the Greybeards have waited plenty for a Dovahkiin. Waiting a little while longer won't hurt them too much
