If you're thinking about becoming a freelancer, you should consider whether you have the necessary qualities. Some people can be better candidates for freelance work than others. One of the most important things is that you need to be self-motivated if you want to be able to find and carry out your work. Although you will often have a client setting deadlines for you or pushing you to complete your work, it's up to you to find new opportunities. You need to be able to organize yourself and come up with a plan for where your freelance work will take you.
You will probably also want to consider what reasons you might have for taking up freelance work. Some people want to do it because they need a way to build their skills outside of their main job. Others want more flexibility in their lives so that they have more control over the work that they do and when they do it. Perhaps you're looking for a way to be your own boss, whether you start freelancing on the side or you decide to commit to freelancing full-time straight away.
