Things will get better if you just hold out long enough.
Every now and then I meet someone certain of personal greatness. I want to pat this person on the shoulder and mutter comforting words: "Things will get better! You won't always feel so depressed! Cheer up!"
As long as you're alive, there's always a chance things will get better.
For optimists, human life never needs justification, no matter how much hurt piles up, because they can always tell themselves that things will get better. For pessimists, there is no amount of happiness—should such a thing as happiness even obtain for human beings except as a misconception—that can compensate us for life’s hurt.
Things will get better - despite our efforts to improve them.
