Aspects feel like they have too many requirements right now.

Clear: Be worded that it can be invoked during regular play.
Compelling: Reveal something interesting about the character.
Double-Edged: Have elements that are potentially both positive and negative.

These are the requirements of aspects, and you're gaining/losing one every level (I'm not sure if it means you gain 1 and lose 1 each level, or you can gain/OR/lose 1.

So you have to make an interesting feature for your character that's both positive and negative, and sum it up in 3 words for your sheet, then completely ditch it in a level or come up with new ones.
