Fermentation temperature control. Research "swamp cooler". And patience. If you do not have a hydrometer, get one. Don't go by the time scale in the recipe, go by the gravity of the wort. Longer fermentation is usually better than shorter. You do not have do do a secondary. 2 - 3 weeks in primary then bottle. Bottle condition for 3 weeks at about 70 degrees then chill one for a couple of days. If the carbonation is low, wait longer.
