Why invest time and energy to look back at where we've been?

I'm one of those people who will only invest so much time into a game.

They had not invested so much time and money simply to see social justice done.

Since these workers were not around very long, it made no sense to invest much time or money in their training.

Maybe I would be better investing my time in something else.

You should be prepared to invest time and money into the process.

First, be prepared to invest time in getting ready for each one.

I chose to invest all my time in high school.

People who are prepared to invest time, skills or money often do not know how to go about it.

Yet a few people, at least, are willing to invest time and effort to make sure that it has a future.
