However, keeping all that digital data in an on-line filofax (i.e together) will not only keep your day-to-day existence in order but also allow anyone, at any point in time, to jump in and take over what you have started. Just hand over one set of log-ins and they have access to a dashboard running your entire business, most of it automated. Simples!!
No business can rely on one person. That is far too dangerous and risky.
