To all you rich players... How did you do it?

Look at the market board often and study it for trends. If you see a "gap" in something with high demand fill the need and reap higher rewards than normal. Accessories make a ton of money for limited crafting time, but not so much right now since its right before a big patch. Raid food and Pots always make good steady money. If you see something that turns over quickly and it is really devalued sink a bunch of money into it and sell it in bulk with a major markup. This works really well with Raid Food and Potions since by the time people make more you've likely sold your entire stock and even if not you listed for higher so you'll still make a bunch of money by the time everything sells. What else... glam gear can sell for a lot of money, but often sell infrequently. Make only one at a time as someone may come along and devalue the hell out of it. All I can think of atm.

EDIT: Oh and I also do most gathering for myself(all 70 gatherers). Except for Aethersands as those take up way to much time and they're usually pretty cheap in comparison to what you're going to make back. Also, undercut by 1 gil when possible. Not much is more annoying as someone tanking the price of something causing everyone to lose money. Though this can also be a good tactic if done right. If someone is active in undercutting you, then you can severely devalue it to the point where you can just buy up their entire stock and relist for a higher amount. This does contain some risk though as if the item is not in high demand and selling often someone may come along and list more before yours sell causing another listing war losing you money. Final tip is diversify. Don't focus all on one item or market. Make sure your spread out so if one market is slow you can expand in another.
