If you don't feel like you are better off now than at some previous point in your life, don't worry, man, statistically you're doing fine. Just fine.
Let's all just chant that, shall we? "Statistically we're all doing fine".
No, wait. Try this: "Statistically we're all doing better."
And then you could try repeating: "I'm just a big baby and a whiny person in general. Look how happy other people are. There's just something wrong with me personally."
I feel better already - how about you?
Some more chanting, eh?
That's a good boy. That's a good boy. See? It works!
