"I think it's dangerous to be optimistic. Things could go terribly wrong virtually overnight"

This quote by Nicholas D. Kristof suggests that optimism can be a double-edged sword. On one hand, optimism can be a great incentive and can help us to attain our goals. On the other hand, it can cause complacency and a false complacency. Kristof is cautioning us that we ought to not be too optimistic, as things can alter rapidly and drastically. He is recommending that we need to be gotten ready for the worst, as it can occur at any time. This quote is a reminder that we must not take anything for approved which we should always be gotten ready for the unforeseen. It is important to remain vigilant and to be familiar with the possible risks and threats that can arise. By knowing the possible threats, we can be much better prepared to face them and to take the required steps to protect ourselves.
