This course helps you build skills to choose high-impact work, design time effectively, delegate and scale with systems, and sustain momentum through energy, email, and reflection practices.
Following the Guide's core premise that "you can't get it all done, so choose what matters," this course builds the judgment and language to identify high-leverage work, decline or defer the rest, and commit via concrete, if-then plans.
Scale execution through others and through rituals: identify "who's got the monkey?", choose the right delegation level, and design energy-aligned routines (90-minute cycles, 18-minute plan, 10-minute diary).
Productivity lasts when energy, tools, and norms are sustained. Manage energy (sleep, nutrition, breaks), iterate on email experiments, and run maintenance cycles to keep momentum alive.

I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

It's an amazing product and exceeded my expectations, helping me prepare for my job interviews. Hands-on learning requires you to actually know what you are doing.

I'm really impressed by the AI tutor Cosmo's feedback about my code. It's honestly kind of insane to me that it's so targeted and specific.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
