I have come across this numerous times when talking with or working with freelancers. Some are just starting out, while others have been freelancing for some time. But they all doubt themselves and feel they are not yet ready to get started, or not ready to approach larger clients, or not ready to charge more for their services.
If that sounds a little like you, I have some good news. (Or bad news, depending on your perspective.)
If you struggle with insecurity, you’re not alone.
