Building a freelancing playbook for web developers — would love your feedback

I've been working on a project for the past few weeks and thought this community would be a good place to get honest feedback.

I'm writing a practical freelancing guide specifically for web developers—whether you build with traditional code, WordPress, or AI coding tools.

The problem I'm trying to solve is simple:

Most developers know how to build websites.

Very few know how to consistently get clients.

As I started writing, I realized most freelancing advice falls into one of two categories:

Very generic business advice.
Success stories without a practical system someone can actually follow.

So I'm trying to build something different—focused on things like:

Positioning yourself
Finding clients
Pricing projects
Discovery calls
Proposals & contracts
Delivering professionally
Building repeat business

One thing I've learned while writing is that getting clients is usually less about technical skill and more about positioning, communication, and consistency.

I'd genuinely love to hear from developers here:

What was the hardest part when you started freelancing?
What's one piece of advice that actually helped you?
What's a myth about freelancing you think people still believe?

If you'd like to see what I'm building, here's the waitlist:

I'm mainly here for feedback, so don't hold back if you think I'm missing something.
