Not everyone is satisfied with the FAE standard approaches of Careful, Clever, Flashy, Forceful, Quick, and Sneaky. Your game might decide to use different approaches.
For example, a GM might decide to emulate the classic Marvel Super Heroes roleplaying game, and choose seven Approaches: Fighting, Agility, Strength, Endurance, Reason, Intuition, and Psyche. Character aspects would continue to define an individual character's skills and areas of expertise.
When changing the number of approaches from six, try to maintain a pyramid structure for the approach bonuses. For example, with seven approaches, the GM might tell the players to pick a single +3, two +2s, two +1s, and two +0s.
A mixture of standard approaches and the Freeform Skills optional rule in the Fate System Toolkit (found here: http://fate-srd.com/fate-system-toolkit/other-solutions#freeform-skills) might revolve around themes: the GM selects three campaign themes (like Violence, Honor, and Legacy), and let each PC pick three personal themes relevant to their character (like Revenge, Love, and Mystery). Characters roll on the appropriate theme when acting to further that type of story within the game.
