What could you let go of, for the sake of harmony?

A prompt from the Jetpack on my WordPress ( which I rarely use) . But as I’ve not been blogging lately , here goes :I’m using the prompt.
Particularly as there appears to be some serendipity in this particular prompt appearing right now. Right now as once again reflecting, no grappling with not what to let go but how much and how to do it. So my first reaction is that letting go is more complex and fractured than appears in the gentle unflurried yogi- like phrase of ‘ let go’
The author of article Finding Serenity etc describes the 6 steps involved in letting go,: releasing resentment, control, limiting self beliefs, attachment to past trauma, excessive material possessions . So just fling them off . To be fair, that’s my interpretation. Fling off the myriad of attachments to our life as it is , and then what ? Where are those threads that bind ?
I’m not arguing that we should keep all those bindings, but I am conscious of the complexity of discarding or at least minimising their impact. This is my and, I hazard a guess, others’ pasts.
Life after letting go is a blank slate to write on again . Sometimes there is no more energy or time left to start another story.
But I’m taking this too literally ? Maybe . For me I have woven and continue to weave those resentments, anxieties , memories good and not so good into the fabric of life now as it is being lived. I’m hopeful , always hopeful , that simply being alive is powerful enough to carry me along . The threads are there to remind at times , to caution , to connect. Just not to bind , I’m living my life warts and all.
