A good trick is to find out the things you are required to build and build it in advance, so when the challenges are back you already have them ready. The same thing can be done for recipes (especially long 12h ones), just make sure you don't collect them before the quest is back. I used this on the wonders challenge, and it saves loads of time, I completed all 7 parts of the hanging garden and mausoleum challenges in a day each.
