To my understanding, it's possible to Compel your own Aspects.
Anyone at the table is free to suggest when a compel might be
appropriate for any character (including their own).
But I don't exactly understand how that works. I know good Aspects have both positive and negative implications, but I can only see the Trouble Aspects to be suitable 'self-Compel' candidates.
Can someone elaborate how Compelling your own Aspects work? I'm looking for answers that explain how self-Compelling works at the table (the back-and-forth conversation surrounding the Compel). I'm also looking for answers that can explain the Fate Point transactions in these situations.
