My Inspiration house rule:
"Since I will not be able to keep track of 16+ individual personality traits, ideals, bonds, and flaws, it will be on you to claim Inspiration whenever you play these out. I will always assume you are making a good faith claim. So if you have a personality trait that says, for example, 'I idolize a particular hero of my faith, and constantly refer to that person’s deeds and example...' and you actually do that, say "I'm taking Inspiration for that." Or just output the personal characteristic into the chat. Then mark Inspiration on your character sheet.
The only limitation I'm placing on this is that you can't gain Inspiration for playing the same characteristic twice in a session. If, for example, you've claimed Inspiration for playing to your bond, you cannot earn Inspiration for playing to your bond again this session. You therefore have the opportunity to gain Inspiration four times during a given session - one for each category of personal characteristic."
Then, in certain campaigns, there are options to gain additional Ideals or Bonds based on, say, alignment (when that sort of things is important to the campaign) or membership to an organization. This increases the number of ways you can get your 4 Inspiration per session. You can only have one Inspiration at a time.
