This depends on how much work you have to do and how much you feel comfortable taking on. The more projects you take on, the more difficult it is to juggle them, especially when you take different deadlines into account. While it can be tempting to say ‘yes’ to everyone, especially when you’re just starting out, you don’t want to end up with too much work on your plate either. Taking on a lot of clients can help you keep up a stream of revenue, but you may end up more stressed and may not be able to dedicate enough time to all projects. This can lead to a decrease in the quality of work. So, this will also depend on what type of work you do. If you’re a designer, you may work on only one gig at a time, since they may be large projects and pay well. And, if you’re a tradesman, you can only take on so much work before you run out of hours in a day, for example. If you’re still thinking about how many clients you should have at once, remember that each one will require communication, billing, feedback, etc., which can be time-consuming. And, if you have a smaller pool of clients, it doesn’t mean you’ll be earning less, as you can still set the rates that work for you.
