Brené Brown, period.
The works of sociologist Brené Brown are brilliant and can help you improve your self-worth and your ability to connect with others authentically. Her TED talks are a great place to start (be sure to watch them in order). I also recommend any of her books, including:
A New Earth: Awakening to Your Life’s Purpose by Eckhart Tolle
The Power of Now by Eckhart Tolle
Man’s Search for Meaning by Viktor Frankl
Stop Walking on Eggshells by Paul Mason and Randi Kreger
Life Skills for Adult Children by Janet Woititz and Alan Garner
The Gift by Hafiz
The Prophet by Khalil Gibran
The Fiddler in the Subway by Gene Weingarten
The Gift of Fear by Gavin de Becker
