It's not what you know, it's who you know. Right? Well, the more honest axiom would be, "It's not what you know, it's who you know and how well you spend time caring for and cultivating those relationships." Not as catchy, but hits considerably closer to the truth. Your success correlates much more to the number of quality connections you've created than your ability to scroll through a contact list of bigwigs.
We always hear about how building a business is about building relationships. However, this usually concentrates on macro-level customer and partner interactions. But the same can be said for every aspect of a business. From the corner office to the mail room. From your water cooler provider to your highest volume supplier. Every relationship counts. Every single bond will play a role in your ability to perform your job at its highest level, be it getting a colleague to help you hit a deadline or a customer deciding not to jump ship after you make a mistake.
The key is to better connect with the people around you and Inc.com has some great suggestions on how to get that accomplished. It takes time and a lot of care, but by making the effort you will be building the path of least resistance to reaching your daily goals.
