From The 50th Law, by Robert Greene and 50 Cent:
You do not wait for things to get better—you seize this chance to prove yourself. Mentally framing a negative event as a blessing in disguise makes it easier for you to move forward. It is a kind of mental alchemy, transforming shit into sugar.
No matter how much money or resources you have accumulated, someone will try to take them from you, or unexpected changes in the world will push you backward. These are not adverse circumstances but merely life as it is.
What you must do instead is accept the fact that all events occur for a reason, and that it is within your capacity to see this reason as positive. Marcus Aurelius compared this to a fire that consumes everything in its path—all circumstances become consumed in your mental heat and converted into opportunities. A man or woman who believes this cannot be hurt by anything or anyone.
If you buy the book (and I recommend it, because it’s great), then go for the paperback. Not only is it easier to make notes, but did you see the Kindle price? $14.99? Do they secretly want people NOT to buy the ebook?
