The real question here is about experience vs reflection on the experience. Do you do both in equal amounts or do you rarely reflect on your experiences, weave them together, look for patterns, and wonder what you have learned?
Anything and everything can inspire poetry if you are reflective.
Shoutout to wasoxygen as we almost discussed this at one point.
A couple friends of mine like to demand stories of me for their entertainment and I often struggle to come up with anything on the spot. It's not for a lack of stories because I embarrass myself, take foolish bets, and meet interesting enough people to have a few stories that I can embellish a bit to give them what they are asking for. But it's still hard for me to categorize and store the things that happen to and around me. I don't reflect on my experiences very much and it takes some external trigger to remind me of the things in my life worth reflecting on.
It may be that I have a poor memory, but I think the problem is that I don't spend enough time or effort to be reflective. The problem goes further than a lack of instant stories to tell my bored friends. I think a symptom of not being reflective is that I don't learn from my mistakes as you mentioned in the prompt. Many of my experiences share similar themes and results that could be changed if I desired and if I spent a bit more time learning from my past.
Good prompt that has shifted my experience/reflection percentage towards the latter, at least for the night.
