Self-confidence plays a key role in how we show up at work, in relationships, and in life. We all possess it. Most of our achievements we’ve made so far has been built on moments of believing in ourselves. Yet over time, confidence can become suppressed, shaken, or simply fail to grow as it should.
That’s when you might start feeling like you’re holding back. Like you’re not quite getting what you deserve, or you can’t fully be yourself in professional or social settings.
The good news? Confidence isn’t something you either have or don’t. It can be rediscovered and strengthened. With the right support, tools, and space to reflect. That’s exactly what this one-day workshop offers.

The approach
At OakTreeMe, we don’t believe in quick fixes or “one-size-fits-all” advice. Everyone’s story is different. That’s why our approach is personal, experience-based, and grounded in real human insight—not just theory.We create a safe and engaging space to reconnect with your authentic confidence.
Participants will explore the root causes of self-doubt, uncover limiting beliefs or hidden fears, and learn how cultural background, inner narratives, and personal values shape their confidence.
Through a dynamic mix of reflection, practical exercises, and some light role play, you will (re)discover the deeper source of your confidence—and learn how to anchor it in your daily life.
The experience
This is not a lecture: it's an active, down-to-earth, and engaging workshop that makes space for reflection, practice, and connection with others and designed to create lasting impact. You’ll leave with more clarity, more energy, and a stronger sense of yourself—and how to bring that into the world.
