The correct answer to this open question is the following.

You did not include any references, context, or any specific situation or statements. At what time you are referring to? Today? The past? Any specific time in history?

We are going to assume that you are referring to living in the present time. If that is the case, then our comment would be the following.

It is important for people to live in the present time because it is the "now moment," the only one that they have.

It is so difficult living in the past because people suffer so much for the things that happened or the things that never happened. But that is out of your control. It is painful, indeed.

Trying to living in the future just generates anxiety because you are worried about what is about to come or what you expect, and it may never come. Or not in the way you are thinking.

That is why the best option is to focus on the now moment, the present. It is the only time you can control. So invest you now time in the best way possible.
