In today's fast-paced world, the ability to perform quick mental calculations gives you a competitive edge in business, academics, and daily life. This course teaches proven techniques used by math champions and accountants worldwide to perform complex calculations in your head. You'll learn tricks for multiplication, division, percentages, and estimation that will make you the go-to person for quick number crunching.

Businesses, investors, and professionals need to gather intelligence on competitors, markets, and trends. This course teaches competitive intelligence techniques: identifying information sources, analyzing competitors, tracking industry trends, using business databases, and synthesizing intelligence into actionable insights. You'll learn to research like corporate analysts and consultants.

Statistics appear everywhere—in news, business reports, and research—but many are misleading or misunderstood. This course teaches you to critically evaluate data visualizations, understand statistical significance, spot data manipulation, and ask the right questions about any statistic you encounter.

Whether you're writing a thesis, researching a business decision, or just want to understand a topic deeply, research skills are essential. This course teaches efficient database searching, source evaluation criteria, note-taking systems, and proper citation methods. You'll learn to find peer-reviewed articles, gray literature, and authoritative sources quickly.

Sometimes the best solutions come from unexpected angles. This course teaches lateral thinking techniques developed by Edward de Bono and other creativity researchers. You'll learn to challenge assumptions, reframe problems, and generate unconventional solutions through provocation and random stimulus techniques.

Many problems recur because we address symptoms rather than underlying causes. This course teaches systematic approaches to root cause analysis, including the 5 Whys, fishbone diagrams, and Pareto analysis. You'll learn to distinguish between correlation and causation and avoid jumping to conclusions.

This course teaches systematic approaches to root cause analysis, including the 5 Whys, fishbone diagrams, and Pareto analysis. You'll learn to distinguish between correlation and causation and avoid jumping to conclusions.

Design thinking is the creative problem-solving approach used by top companies like Apple, Google, and IDEO. This course teaches you to empathize with users, define problems correctly, ideate creative solutions, prototype quickly, and test iteratively. You'll learn why jumping to solutions fails and how to approach challenges systematically.

Memory champions use spatial memory techniques that anyone can learn. This course teaches the memory palace method (method of loci), peg systems, and other mnemonic devices used since ancient Greece. You'll learn to memorize speeches, lists, numbers, and complex information without rote repetition.

In the information age, reading speed is a competitive advantage. This course teaches proven techniques to dramatically increase your reading speed while improving comprehension and retention. You'll learn to eliminate subvocalization, expand peripheral vision, and adjust reading speed based on material type.

Based on cognitive science research, this course teaches the most effective learning techniques—many of which contradict popular study habits. You'll learn about spaced repetition, active recall, interleaving, and the testing effect. Discover why highlighting and re-reading are inefficient and what actually works for long-term retention.

Fake news, deepfakes, and algorithmic manipulation make it harder than ever to know what's true. This course equips you with critical thinking tools to evaluate sources, verify claims, and navigate the information landscape confidently. You'll learn how algorithms shape what you see, how to trace information to original sources, and how to identify subtle bias and manipulation.

Every important decision involves incomplete information and competing priorities. This course teaches frameworks used by top executives, military strategists, and poker champions to make better decisions under pressure. You'll learn probabilistic thinking, scenario planning, risk assessment, and how to avoid common cognitive biases.

In the age of misinformation, the ability to identify flawed reasoning is essential. This course teaches you to recognize and avoid the most common logical fallacies—from ad hominem attacks to straw man arguments. You'll learn to construct sound arguments, spot manipulation tactics, and think more clearly about complex issues.

Biohacking uses science and self-experimentation to optimize physical and mental performance. This course teaches evidence-based biohacking strategies: nootropics and supplements, cold exposure and heat therapy, light optimization, intermittent fasting, and tracking metrics that matter. You'll learn to separate biohacking fads from scientifically-supported interventions.

Your body is an incredibly complex system, yet most people know surprisingly little about how it works. This course explores human anatomy and physiology in practical, relevant ways: how your immune system protects you, what happens when you exercise, how hormones affect mood and behavior, how digestion works, and what your brain does all day.
