Your expectations can make things more difficult for me than they would otherwise be if you didn't consider me a magician.
Or they can make things go better than they would otherwise go for me if you just name me the sole person in your will.
With expectations in general, much depends on what you expect. Positive expectations often pave the way for positive experiences, but they hardly get anyone to do your laundry.
Other people pick up on your expectations and, more often than not, will work hard to disappoint you. So it pays to expect the best of others when it comes to your expectations and it costs nothing to expect the unexpected of someone else's expectations.
The person most influenced by your expectations is your religious leader. When you genuinely expect the best of yourself, your religious leader tends to imagine that you will be giving about ten percent of your salary to his organization. And something inside you will do everything possible to deliver. Go figure.
The great thing is, your expectations are yours to decide. Don't go deciding the expectations of others, unless you expect them to do nothing, in which case they will live up to all expectations. And when you make an expectation, demand that you fulfill it by four the next afternoon, at least. Tell yourself that it is important, even if your loved ones are ready to call the police.
No complex skills or scarce resources are needed in order for you to expect the best of yourself, of others, of this day and this moment. Unless your only friends belong to the Taliban. Then, I would rethink the whole process.
Your expectations set the range within which your reality operates, and after such an operation, it is common to get an autopsy. Expect the best, and you greatly increase your chances of getting it. Expect the worst and not only will bad things probably happen, but the good things you should have expected can also still happen.
