Self-development book

[HolidayHunter7]

Anyone read a great self-development book that they would recommend?
My brother enjoys these, and he’s feeling a little lost/looking for purpose in his life at the minute, so I was hoping to find a book related to this.

Thanks!

Look on The School of Life Website- loads of good ones.
The one I read thar literally changed my trajectory for the better in life was Daring Greatly by Brene Brown

Philosophy for Life by Jules Evans - really good read and not self-helpy but every day wisdom on how to live well

Feel the Fear and do it Anyway.
Susan Jeffers.

Thanks all, I’ll look into these!

Atomic Habits by James Clear. Life changing.
