Prevention is better than cure
To grow a valuable business – one you can sell – you need to set up your company so that it is no longer reliant on you.
This can be easier said than done, especially when, like a PR consultant or plumber, what you are selling is your expertise.
To scale up a knowledge-based business, you first have to figure out how to impart your knowledge to your employees, so that they can deliver the goods. However it can be difficult to condense years of school and on-the-job learning into a few weeks of employee training. The more specialized your knowledge, the harder it is to hand over work to juniors.
