The Comfort Book by Matt Haig is a nice read made up of short vignettes, with below from some of them:
A thing my dad said once when we were lost in a forest - If we keep going in a straight line, we'll get out of here.
It's okay - It's okay to be broken. It's okay to like what you like. It's okay to be who you are.
Power - Our perspective is our world, and our external circumstances don't need to change in order for our perspective to change.
To remember during the bad days - It won't last. You have felt other things. You will feel other things.
One beautiful thing - Experience one beautiful thing a day. Just give yourself one simple reminder that the world is full of wonders.
Rain - You don't have to be positive. You don't have to feel guilty about fear or sadness or anger. You don't stop the rain by telling it to stop. It never rains forever. The storm may knock you off your feet. You will stand again.
Experience - We are not what we experience. If we stand in a hurricane, it doesn't matter how violent or terrifying the hurricane is, the hurricane is not us. The weather outside and inside us is never permanent.
Ferris Bueller and the meaning of life - This is a movie about Cameron. He is the emotional center of the film and makes the most significant transformation.
Growth - We grow through hard times. Growth is change. When everything is easy, we have no reason to change.
Clarity - You are here. And that is enough.
Realization - I used to worry about fitting in until I realized the reason I didn't fit in was because I didn't want to.
Aim to be you - If you aim to be something you are not, you will always fail. Aim to be you.
Forgiveness - Forgiving other people is great practice for forgiving yourself when the time comes.
