The future is a mystery because it is something that has not happened yet and is therefore unknown. We can make plans for the future, but we cannot know for sure what will happen. The future is full of possibilities, both good and bad.
The present is a gift because it is the only moment that we have control over. We can choose how to spend our time in the present, and we can make the most of it by living in the moment and appreciating what we have.
That's why it's called present.
