Ask HN: What are the most effective forms of emotional conditioning?

I don't mean Pavlov. I'm talking about mental toughness. Emotions are arguably the most important thing to manage in life. In some respect, that's what we do all day long.

I'm wondering if any of you know of any techniques to become emotionally stronger/resilient.

The most effective strategy I have found is listening to motivational/positive audiobooks.

Boot camp? I started making a list of hypothetical situations that would elicit the most nervousness/fear from me in various parts of my life (career/spiritual/relationships/health/etc). Just writing the list was difficult. Anyways, made me think some smart guys hear would have some hacks for managing emotions.
