My wife says our kids make us smart. She means that our daughters make us aware of things in the world that we otherwise would know nothing about.
For example, when our girls were small we became very familiar with a parallel universe of:
Safety: outlet plugs, edge and corner guards, bathtub seats, back-facing car seats, baby monitors, water wings.
Books: When Hippos Go Berserk, Moo Baa La La La, The Very Hungry Caterpillar, Chicka Chicka Boom Boom, Lily’s Purple Plastic Purse, We’re Going On a Bear Hunt, Pigs Aplenty Pigs Galore (my favorite).
Entertainment: The Wiggles, Blue’s Clues, Veggie Tales, Dora the Explorer, Teletubbies, Jimmy Neutron, Spongebob (actually, our daughters still watch Spongebob).
Clothing: Gymboree stuff was awesome; it was comfortable, cute, and durable.
If I returned today to the land of little people, I would be clueless about nearly everything. Well, maybe not totally clueless; some things undoubtedly have endured.
Our markets can be similar. When we are immersed in the world of our buyers, we not only know what their needs are, but we can anticipate what they will require in the future.
But if we become detached, or think we know everything there is to know about our niche/market, we lose sight of our buyers and don’t understand their pain. Revenue eventually slides.
As you continue your continue your solopreneurial journey, consider what it’s like to be a parent of young children. Figuratively get on the floor with your market and play, teach, ask questions, listen, learn.
