What subject/struggles touches most of us?

Good afternoon all,

I’m currently working on a project to help uplift people (It’s about finding balance between mind, body and soul)

Can you guys suggest things that touches all? Subject where you would like more explanation on or how to overcome things and/find peace in your life.

Thank you in advance, I’m not perfect and I too experience struggle at times and I’m still working on it!

Have a lovely day all!
