A vehicle can help you get from point A to point B very effectively... if you have all of the following components.
You need gas in the tank.
Wheels on the ground.
An engine that runs.
You need a driver.
Then you need to know your starting point and destination.
Without directions and a driver ready for the journey, the vehicle doesn't move.
You may think your business needs Systems, Team Training, External Marketing... but this is just the gas.
The success in your business comes down to the driver's (you) ability to make the trip and not allow the potholes, speedbumps, hills and valleys (these are your "Interferences To Growth") to prevent you from completing the journey successfully.
