To each their own, but this one resonated deeply with me:

Again, when you’re surrounded by other people all the time, you’re constantly trying to read, and cater to, the other persons’s emotions. So much so, that you could end up losing touch with your own.

When you start to enjoy being alone, you’ll gain a greater perspective for your own emotions. You’ll create a deeper understanding of what makes you happy, what upsets you, and what saddens you.

With that knowledge, it’s then easier to regulate your emotions. But it all starts with understanding how you feel, and that comes from a little bit of solitude.

Just as long as those emotions aren't loneliness and sadness.
