Nothing secret...but if your property can support mining drills stone is hot right now. Or if your in a guild you can technically run traderuns all day until you are bored to death. Sell what's hot....chicken eggs, leather, fabric, stone, coral, etc. Labor regains so fast you can pretty do whatever you want to make some income, raise your fishing to 20k with the fishing pools and sell or use the dawnslake ess....get a clipper and go fishing somewhere close to a turn in.
