Are you really learning as effectively as you think, or are hidden mental shortcuts holding you back? This episode involves a 'Masterclass' in which we unpack the world of cognitive biases and mental bottlenecks in learning—those subtle psychological tendencies that skew how we perceive, absorb, and evaluate information.

• Get Real About Skills: The Dunning-Kruger effect and why it’s easy to overestimate your know-how.
• Stop Overselling Yourself: Overconfidence bias—and how to finally see where you stand.
• Balance Your Study Time: The hard-easy effect and finding that sweet spot between basic and tough stuff.
• Bust the Illusion of Competence: Why re-reading and highlighting aren’t cutting it for real understanding.
• Beat the Clock: The planning fallacy and simple hacks to finish projects on time.
• Ditch Perfectionism: When “good enough” is actually the key to better performance.
