Pretty much everything you decide to do adds value in one way or another. Sometimes, the value of a task or job may not be apparently clear. For those situations, I like to use the following preposition:
“The point here is”
It’s a good way to focus your attention to the impact of a task, a change, or a decision. If you can’t finish the sentence and explain the value of what you’re working on, then it might be a good time to think about doing something else.
