I just finished Dream Big by Lisa Hammond aka The Barefoot CEO and Founder of Femail Creations. Her e-newsletter is Girl Talk.
Lisa created Femail Creations - a website and catalogue which showcases cool stuff by women, for women - and was recognized as a Small Business Association Business Person of the Year 1 year after being denied her first loan. What I love is her chutzpah and her willingness to "just dive in" sans business plan.
In marketing and in real life, I think it's important to meet people where they are. Including OURSELVES! Sometimes you can't determine where you are going until get going. And that's ok. This is also Julie Chapman's advice. She is my beloved boss and terrific mentor. Execution, i.e. getting stuff done, is more important than planning any day. So get ready, fire, then aim.
