How Thais Gibson built a $2–5M personal development school

Thais Gibson

The Personal Development School

Thais founded The Personal Development School (PDS), an online education platform that helps people master emotional healing, attachment styles, and relationships. With 65+ courses, memberships, and certifications, PDS is now estimated to generate between $2–5 million a year.

She turned academic psychology into something practical and relatable. Instead of vague self-help, she teaches specific frameworks - like her Integrated Attachment Theory™ - that give students immediate clarity about their emotional patterns and actions. This focus on real, measurable change keeps members subscribed.

Most new students find PDS through YouTube, where Thais posts free lessons on attachment and emotional regulation. Viewers take her free “Attachment Style Quiz,” join her email list, and are then invited to join her membership or certification programs. Free content builds credibility, while the quiz drives steady lead flow.

Start with overlap. The best idea sits where your experience, your interests, and real market demand meet. If you only pick passion, it might not sell; if you only chase profit, you’ll burn out.

Look at what people already ask you for help with. Those questions are signals of unmet demand. Build from there instead of guessing or copying trends.

Choose one big goal for this month and break it into three daily habits. Example: if your goal is to start an online business, your habits might be (1) research for 15 minutes, (2) write one idea, (3) learn one tool. Progress compounds through small, repeatable action - not random bursts of effort.
