How to Foreshadow Without Revealing Too Much?

Hey everyone,

I’m currently writing a novel and have completed three chapters, but I’m struggling to move forward. My main character has a complicated past, and I don’t want to reveal it too early in the story. However, I do want to foreshadow it in a way that keeps readers intrigued.

The problem is that every time I try to progress the plot, I feel like I’m either revealing too much or not giving enough hints for readers to stay curious. I’m looking for advice on how to organically weave in foreshadowing without outright exposing my MC’s past too soon.

If you have any techniques or examples that could help, I’d really appreciate it!

Thanks in advance!
