Social Entrepreneurs and Life's Buffet

new author publishing at worldchangingbook.com

I'm a college teacher and an author who wants to change the world. I've written an engaging book letting young adults 18-28 know about ways that they can do work that helps change the world ("fixing" poverty, education, the environment, ... ) AND make a living.

18-30 year olds, probably with some college. Of course, this group is very web savvy (so nothing stuffy, please!). I'm trying to let them see that they can take some action to _design their life_ (instead of just waiting for it to happen), and end up working on truly meaningful assignments AND make a more than decent living

I am looking for a BOOK COVER. I want to make sure that the cover looks good on the physical book (6.75 in X 9.5 in), but it also MUST look good as an AMAZON thumbnail. (Note: Amazon prints tiny, medium, and large thumbnails -- it must look good in the medium and large size)

What does "look good" mean to me?
a) the title should be *legible*. This is important
The Title
Social Entrepreneurs and Life's Buffet:
Design Your Life, Change the World.
KEY PHRASES in the title are
"Social Entrepreneurs" <-- people who invent social ideas to help change the world
"Design Your Life" <-- the idea is that you can balance your desire to DO GOOD and still make a good living

b) ideally, the cover suggests some kind of growth (a plant?), or hope, or change. There is a strong theme of "innovation" in the book, too.

Two examples of covers that I like, because they are legible as Amazon thumbnails are:
1) Ten Ways to Change the World in Your Twenties ... (Libuse Binder) It's "clean," suggests "change," and is legible.
2) "Building Social Enterprises: The New Kind of Capitalism that Serves ... " (M. Yunus)
What I like about this is how both the author's name (Yunus) and the Title stand out. I like the dark and light contrasting fields, too. I want my title to be legible (much less so my name) and this format could work.

Include my name for now, John Doe is fine
