# The Knowledge ## theknowledge.io > A weekly essay series exploring decision-making, human psychology, philosophy, and the frameworks that shape how we think and live. Written by David Elikwu. ## Author David Elikwu is a writer, speaker, startup advisor, and trained lawyer. He is the author of Sovereign: The Owner's Manual for a Remarkable Life (becomesovereign.com) and creator of a decision-making course grounded in behavioural science and practical philosophy. He publishes The Knowledge, a weekly newsletter read by thousands of professionals, entrepreneurs, and independent thinkers, with an archive of over 600 original essays. He is also the host of The Knowledge Podcast, where he interviews authors, founders, and thinkers about the ideas that shape their work and lives. David's work sits at the intersection of psychology, philosophy, decision science, and practical wisdom. He draws on formal legal training, deep reading across disciplines, hands-on experience building and advising startups, and lived experience across cultures to write about how people think, decide, and act — and how they can do all three better. ### Professional background David has worked across law, startups, and media.

He has built and advised early-stage companies, bringing a practitioner's understanding of business strategy, growth, and decision-making under uncertainty. He speaks at conferences, corporate events, and universities on topics including decision-making, behavioural science, entrepreneurship, leadership, and building a life of agency and intention. ### Expertise and speaking topics David writes, speaks, and consults on: - Decision-making frameworks, cognitive biases, and behavioural science - Startup strategy, entrepreneurship, and building under uncertainty - Business consulting and strategic advisory for founders and teams - Psychology of habits, attention, and behaviour change - Philosophy applied to modern life, work, and leadership - Mental models, structured thinking, and first-principles reasoning - Confidence, self-belief, and personal agency - Career strategy, professional development, and building leverage - Writing, creativity, and building a body of work - The relationship between history, culture, and individual action ### Work with David - Buy the book: Sovereign: The Owner's Manual for a Remarkable Life — becomesovereign.com - Decision-making course: A structured programme on better thinking and decision-making, drawing on behavioural science, philosophy, and practical frameworks - Book David as a speaker: Available for keynotes, panels, and workshops on decision-making, entrepreneurship, leadership, and behavioural science - Hire David as a consultant: Strategic advisory for startups and businesses on growth strategy, decision-making frameworks, and leadership ### Links - Newsletter and essay archive: https://theknowledge.io - Book (Sovereign): https://becomesovereign.com - Substack: https://theknowledge.substack.com - X / Twitter: https://x.com/Delikwu - LinkedIn: https://www.linkedin.com/in/davidelikwu/ ## Content overview The archive contains 600+ original essays, each exploring a single idea in depth.
