Here's what I think! Why don't you take a rest and cool down? You can Auto-Craft while you do it, so you don't feel like you're wasting your time. Also, you'll learn a little patience. Heh heh... Don't forget. Press Z! Of course, this only works when crafting something!
Get the supplies for something that doesn't cost to much to craft. Then simply press Z and wait patiently for your items to be crafted. After all have been made, talk to the NPC to complete the quest. Easy huh?
