HoPe Vs ExPeCtAtIoN

What is the difference between expectation and hope? Hope is what keep human alive, if we don't have hope we might as well consider our self dead. Because once you lose hope, you won't have any spirit to live your life. On the other hand, Expectation, whenever it doesn't meet reality, is the biggest source of our frustration, anger, sadness. Expectation and hope are only separated by a fragile thin line. If we hope for something but we want that something to happen so bad, we will break that thin fragile line and then what originally our hopes turn into expectations. That's when what originally our source of life spirit turns into source of our frustration, anger and sadness. We will always feel trouble by what originally something that keep us living.
