These are good to read, period. And, these are excellent mood uppers!
Sometimes the idea of reading a book, especially when one is unmotivated, is not motivating! But reading quick summaries of great ideas and great thinking provides easy and incredible thinking that can't help but be stimulating and inspirational - as you fill your mind with positive materials and potentialities!
The summaries idea below is, I think, the best idea for quick inspiration.
THE BEST BOOKS FOR INSPIRATION
I'm listing a few here that are for "quick inspiration", but continue on to the rest of the list: The Best Books List, which classifies what is inspirational, most useful, etc.
Quick Inspiration Summaries Books
Self Help Stuff That Works (50 summaries), Kahn
The excerpts of, or the full set of, summaries of 100 books listed on

Year To Success (thick, good), Bo Bennett

You can flip through these rather easily and quickly to find something of interest and inspiring. I put these all together on one book shelf, so I could access them when I was at "loose ends" for some reason.

PhilosophersNotes.com - Although you'll have to shell out about a $1 each (and buy a 100 at once), these 6 page summaries and their MP3 versions are the best and easiest way to search for what might be of interest and to read (review) the key ideas. (Click on "Books" and see the list plus some samples, which in themselves, provide stimulating thoughts!)
