When I have no clients or projects as a freelancer , What should I do?

Hi everyone,
hope you are doing great. Today i want to discuss a topic as mentioned in title. As a freelancer what should we do in our free time?
According to me we learn any new skill related to our field.
like if you are a web developer you can learn any new language like laravel / php or you can learn any new js framework. if you already learn then you can create an app or website for practice. you can work on your portfolio.

I advised you to never stop learning. Doing Something great all time. Try to learn and explore more new things.

I hope that's will help you.
Thanks
