There is lots of great business advice that you can read and get on here. Execution matters is the most importantly clearly. Knowing who your customer is, having plans, expecting the unexpected, understanding your market. . . all great advice.
I am going to throw out the one that over my years of facilitating strategic growth initiatives with SMB, family-owned businesses, and start-ups consistently proves to be one of the most important:
Don't have an affair with your business.
Don't forget your own foundation of family and spirit. The fabric of your spiritual, family and friends is your foundation. Don't forget them. You need them. You need their support. You need their love. You need a shared commitment to success. You need them to provide perspective. You need them to replenish your spirit when you get kicked.
Earn the support of your family as you launch.
Sometimes we are so focused on earning investor support, landing beta customers, polish our unique value proposition that we forget to maintain the lines of communication with our friends and family. We expect that they will support us unconditionally and way too often we abuse that unconditional support. Make sure that you provide them the same high level open communication that you would the most important investor -- because they are.
Stay on top of your FRM
Make sure your FRM (family/friends relationship management) is treated as important as your customer relationship management and your investor relationship management. Be transparent with the down -- not just the up. Say thank you. Plan date nights -- and keep them. Create spaces where they can complain about Mom/Dad not being there. And then make sure that you are.
Because in then end -- that is what will always be the most important.
