Know where the work is

My car importing business is about a fun, high performance driving experience. The work, however, is in getting through compliance red tape and providing information to the thousands of people who contact us in the meantime.
Running a caf? is about a great place for friends and family to meet. The work is in early starts, late finishes and non-stop hard slog in between.
Running a telco is about people communicating with each other. The work is in billing correctly and handling a large number of customer interactions efficiently & cost-effectively.
The nature of the work effort in a business is typically different to and less glamorous than the purpose of a business would suggest. Make sure you know in advance where the work is – otherwise you may have significant skill gaps, inadequate systems and a business that you don’t actually want to run.
