Now that sims can gain new traits, anyone know what to do to possible obtain klepto trait?

@mightysprite I will have to try that one out, thanks :)

Here I am, the creator of this thread (my attempt to understand self-discovery system through tuning files)!

Kleptomaniac is under Economy self-discovery category. This means two things:

• You can't have a self-discovery moment for Kleptomaniac if your sim has Materialistic trait.
  
• If your sim has Freegan trait, a self-discovery moment for Kleptomaniac trait will replace it.

While I don't know what exactly helps towards it, looking from notification texts, earning money and spending it on expensive things (artwork for example) can help towards it.
Though your sim can be suggested Materialistic trait instead. Reject it and do the same until your sim gets suggested Kleptomaniac trait instead.
Should you accept Materialistic trait, you could work towards Freegan trait and then towards Kleptomaniac trait again, but should you succeed, all your sim's 3 self-discovery opportunities are spent.

Thank you so much for explaining it to me, I will try this out :)
