Just call him DK.

For years, DK felt like he was always in motion but never truly getting anywhere. With an erratic brain constantly pulling him in different directions, he juggled multiple projects, ideas, and ambitions, only to find himself stuck in a cycle of unfinished plans and fleeting motivation. Frustrated but determined to make a change, Dennis turned to something simple yet transformative: lists (sounds boring, right?).

What started as a way to organise his own chaotic thoughts quickly became the foundation for something bigger, 99 Things. By creating structured, actionable lists that he could refer back to at any time, picking up an action at any point, DK found a way to cut through the noise, stay focused, and finally make progress. Now, he shares his hard-earned wisdom with the world, offering no-nonsense, practical books designed to help people get ahead in life, career, and personal growth.

DK lives in the UK with his small family, balancing the demands of everyday life while staying committed to his mission: helping others break free from overwhelm and start taking meaningful action. He believes in the power of sharing knowledge, offering readers a straightforward, results-driven approach to self-improvement and the power of getting ahead, one small tick off of a list at a time.

DK isn’t here to preach, he’s here to give you the tools you need to get unstuck, move forward, and start achieving real results. Whether it’s acing a job interview, practising self-kindness, or advancing in your career, his books strip away the fluff and deliver exactly what you need: practical steps, real insights, and a roadmap to success.
