Big Trust

Brought to you by Penguin.

Harness the power of self-belief and learn to back yourself, every time

Self-doubt. It’s the silent force that undermines potential, eats away at confidence and traps even the most capable in overthinking. You can’t outperform it, but you can rewire it.

Drawing on leading research, over a decade of work with Fortune 500 companies, and experience educating millions of professionals worldwide, Dr Shadé Zahrai reveals a proven system for breaking the cycle of self-doubt and building deep, unshakable self-trust. In Big Trust she shares her proven framework – the Four A’s: Acceptance, Agency, Autonomy and Adaptability – and shows you how to take control of your inner world so you can thrive in the outer one.

With insights from her self-diagnostic quiz and actionable exercises throughout, you’ll learn to:

• Reframe the beliefs that hold you back
• Break free from people-pleasing and perfectionism
• Quiet comparison and imposter thoughts
• Stretch your comfort zone and reclaim your power
• Channel emotion into clarity and conviction

Whether you’re second-guessing a big decision, overthinking in high-stakes moments or feeling stuck despite knowing you’re capable of more, Big Trust offers practical steps that lead to powerful, lasting results.

Everything you aspire to and the strength to realise it, begins with Big Trust.
