When developing a business, as well as in life, it's vital to keep company with positive people who will support you. The benefits of surrounding yourself with like-minded others can not be stated highly enough, and one way to find those people is to network in appropriate circles.
I recently attended an empowering event by the WIE (Women, Inspiration and Enterprise) Network and was inspired beyond belief. Held in the Dolce Vita Showroom in the Puck Building in NoLita, the atmosphere was both fashionable and fascinating, and filled with infectious energy. Hearing so many accomplished women speak on various topics was electric, engaging and encouraging.
It is also important to become a voracious reader as this fosters your professional development. If reading The Wall Street Journal was not part of my daily routine, I would not have learned of the symposium. Sometimes we only read the "relevant" publications affiliated with our industry, but it's important to understand what's going on in the rest of the world and in other industries, and consuming business publications sharpens your acumen. (The Wall Street Journal, Financial Times and The New York Times should be your go-to resources in addition to your trade publications.)
Much like you have to put in the time in the gym–or whatever your activity–for optimal health and fitness results, you also have to put in the time networking and reading for optimal business growth.
