Q: Do you think the time is important?

A: I think time management is generally important for, say, success in business, but we have to be careful not to obsess about it. I don't think it is happy to be always pressed for time and constantly think of something about the future even if you get a lot of money through it. I think time is just in our imagination, just our invention, so seize the day.

The question is fairly natural.
As for the answer, try combining contractions (example: it is = it's) and replacing and removing some words.

As for a full correction: "I think time management is generally important for, say, success in business, but we have to be careful not to obsess about it. It's not contentful to be always pressed for time and to constantly think about the future, even if you do get a lot of money through it. I think time is just our imagination, just our invention, so seize the day."

I kind of understand what you were trying to say in "I don't think it is happy..." but it's hard to find a natural sounding synonym for the term and the way you used it. I hope this helps.
