Being an independent business person requires you to deal with the ebbs and flows of business since the only constant about business is that it is not constant. Curiously, these various business currents are often described using other water-related words.
On the bright side, every entrepreneur likes a steady stream of customers, not too many, not too few. Some businesses, due to their seasonal nature, require their owners to ride the wave of orders until they can relax in the dead season. In any case, nothing brings a bigger smile to a factory owner than having orders pouring in, allowing them to generate full production capacity. However, it is possible to have too much of a good thing. While a torrent of work may sound like a good thing, the poor freelancer may find him/herself flooded with work, bogged down in various tasks, so swamped that s/he can do nothing else but work or so mired that orders must be refused. The tidal wave can be simply too much for one person.
The other extreme is not any better. While a bit worrying, if work is trickling in or coming in dribbles, there is at least some cash flow. A long flat spell may be sign of changes in the market. The worst feeling is when orders start to dry up and the business is facing a drought. In such a case, it is hard to decide what to do, to have sunny thoughts and wait for a change in the economic forecast or to look for greener pastures elsewhere with less dark clouds.
As we can see, entrepreneurs and sailors must be optimistic about the weather but realistic about its chances.
