What piece of advice would you give your younger poly self?

Curious to see what learnings people have collected from their experiences in polyamory. I’m young and still consider myself new to poly (six-ish years in on and off ENM/poly relationships) and for me it would be to hinge better and keep my relationships more separate. It’s better to let things form organically than to chase KTP or a similar structure because you think it might be best for you.
