Just going through the Dawnstar "Nightcaller Temple" quest, I was reminded of the quests and activities where patience was a virtue. For example, if you do NOT drink Vermina's Torpor when Erandur tells you to, he will walk back to the barrier (where you find him after the dreamstride), where you can then drink it.
Others I have slapped my head at are the 2 dragon shouts you get from The Greybeards, and the one from Paarthurnax. My first time through, I got the new shouts and then went into my character sheet and spent dragon souls to activate them. Then, the Greybeards and Paarthurnax gifted me with the power to use the shouts.
What other places in Skyrim have you found that patience is good thing?
