A basic model to establish a robust income engine: Build skills: Marketable skills (sales, design, copywriting, software engineering, and so on) are assets that you can create and compound. Every new skill is built on top of existing skills to create a unique portfolio. Leverage skills: Strategically deploy the marketable skills to convert them into income. The means of deployment exists on a risk spectrum from stable, lower-risk, time-for-money primary employment to volatile, higher-risk self-employment and entrepreneurship.
