The Five People You Meet in Heaven, a bestseller by Mitch Albom is a novel that if you haven't had a chance to read, you definitely should.
It is a short novel (I'd estimate 50,000 words) and it's an engaging story from start to finish. The lessons learned by Eddie, an amusement park maintenance worker who believes his life was a waste, I think will resonate with just about everyone.
I would break it down to five main themes:
1. Everyone is connected. What you do affects people, in ways you may not realize.
2. Sacrifice, it's something to aspire to.
3. Forgiveness: one must be able to forgive yourself and especially others.
4. Lost Love is still love.
5. Everyone has value and no life is a waste.
Sounds like common sense, but do you really believe those statements? And if you do believe them, do you know someone who doesn't?
It is one of the novels I have taught to seniors where I teach. Almost 90% indicate after reading The Five People You Meet in Heaven, that they really enjoyed it and, better yet, got something out of it.

There is a movie version available on DVD (Starring Jon Voight), and it is a good view after reading the novel. The content and order of the novel is ordered better and adds depth a film cannot. As in many instances, while the movie is good, the book is far better.
