Does this sentence make sense?

For Amber volunteering instilled the desire to use her time more productively and simultaneously make a difference in the community.

What is "Amber volunteering"? Oh, you mean, "For Amber, volunteering ... "

Let me read it again.

It's awfully wordy and stilted.

How about this:

For Amber, volunteering made her want to use even more of her time making a difference in her community.

Or ... since the repetition of forms of "make" is disturbing to me ...

For Amber, volunteering made her want to use even more of her time helping others in her community.

her daily routine after work consisted of grading papers and watching TV so she was looking for ways to spend her time more "productively" after work and decided volunteering would be the best approach. I'm trying to think of a good sentence for all this information

Why is "productively" in quotation marks? Are you quoting someone?

Let me read it over.

Read over this webpage, and let me know which words in your sentence can be eliminated. I'll be checking it, too.

trying to paraphrase what they said

Quotation marks are for the exact words of someone else, whether in writing or speaking. Paraphrasing is what's written in your words, trying to capture the meaning without actual quotation.

How about this:

Her routine after work included grading papers and watching TV. She was looking for better ways to spend time, and volunteering at the Y's homework center seemed a good choice.

That works, but I am going to continue to play around with it a bit. I appreciate you're help Writeacher. You've been very helpful, thank you!
