Knowledge Into Income is a practical guide for therapists who want to turn what they know into a digital product that reaches more people and earns beyond the therapy room.
Fifty minutes at a time. One person at a time. And when you stop working, the income stops with you. You have spent years developing real clinical insight — patterns you recognise, frameworks that shift things, language that lands.
Meanwhile, people who need what you know are searching for it online. Most of what they find was not written by a clinician. There is a gap. This guide exists to help you fill it.
A structured process for identifying what you know, who needs it, and whether there is a viable product in it — before you write a single word.
The 90-day plan, the marketing mechanics, the pricing strategy, and the platform decisions — built for a therapist with a full caseload, not a full-time creator.
Most therapists with postgraduate training write the way they were taught — hedged, referenced, assessed. This guide shows you how to write the way you speak in a good session. That voice already exists. You use it every day.
Dr Derek Nasseri is a UKCP-registered psychotherapist with over 12 years in private practice. He holds a Professional Doctorate in Systemic Practice and a first degree in economics — a combination that shapes how he thinks about clinical expertise and its commercial potential.
He built a full private practice, completed his doctorate, and then wrote an ebook that found an audience he hadn't expected — reaching readers across the UK, the United States, and internationally. Knowledge Into Income is what came out of that experience, and from working with other therapists through the same process.
His first ebook — the proof of concept behind this guide — is Oh, Boy!, a guide for parents navigating emotional connection with boys and young men.
Dr Derek also works with a small number of therapists in a coaching capacity and is building a group coaching community for clinicians creating their first digital product.

Yes. The guide is written for therapists in private practice regardless of location. The marketing section covers both UK and international platforms. Pricing examples use dollars but the strategies work identically in pounds.
If you have a small but real social media presence, or are willing to build one, this guide is designed for you — it works with audiences of under 100 followers. If you prefer not to use social media at all, that is a different route that involves paid advertising rather than content, and this guide is not the right starting point for that. Feel free to email info@itsdrderek.com to discuss which approach fits your situation before buying.
The guide is built around a 90-day plan designed for someone working alongside a full caseload. Most therapists complete their first draft in six to eight weeks, working in three sessions of around 60 minutes per week.
This is one of the most common questions, and the guide has a full chapter on it. The short answer is yes — with the right approach. The guide covers what your professional body actually says about using clinical material, how the composite approach works in practice, and the disclaimer that protects both you and your readers.
As a digital product, this guide is not eligible for a refund once downloaded. What I can say honestly is this: even if the guide does not lead to a commercial product, going through the process of working through it will pull your clinical knowledge into one place in a way that has real value in itself. Many therapists find that the Expertise Inventory alone changes how they think about what they have built over their career.
Almost certainly. The guide includes a validation process that tests whether your idea has a viable audience before you spend weeks writing. Many therapists come in with a clear idea and leave with a sharper, more commercially viable version of it.
