My favorite piece of advice is to treat yourself like a business.

Some people get the idea that freelancing is somehow a separate entity but, in reality, you are simply a business of one.

Freelancers wear many hats, and if you forget to put on of them on for too long, such as your marketing hat, your business can become unbalanced. Even worse, when you have 3-6 months of work lined up you might not even notice right away that your lack of, in this example, marketing efforts are leading you to trouble.

Just because you don't have any caries now doesn't mean you shouldn't be brushing your teeth. Similarly, even when things are going well, it's critical to do the everyday tasks that keep your business healthy in the long run.

Good luck!

Any recommendations on preferred tools for setting up an online portfolio and business site?

I know the big players such as Wix, Squarespace, Wordpress, etc...

Are there any new players out there that might be interesting to check out? Someone recommended Full Scope Freelancer which, tbh, looks pretty good for the price.

Your thoughts?
