Brene Brown equivalent for v young teens

[AnotheChinHair]

I am looking for a no nonsense inspirational book for my 12 YO DD whose self-esteem is at an all time low and has zero confidence. I'd like her to understand how much she can do for herself, etc. Suggestions welcome. Thank you.

"You are awesome" by Matthew Syed, or Diary of a Brilliant Kid by Andy Cope?

Good luck.

Thank you. We have the first one you have mentioned. The second looks great, don't know if it might be a little young for a 12 year old. Would love some more recommendations please.
