The term "passive income" is somewhat misleading — every income stream requires some initial work, capital, or both, and most require periodic maintenance. The IRS defines passive income specifically as earnings from rental activity or a business in which you do not materially participate. However, in popular financial planning, the term broadly covers any income that does not require trading time for money at a 1:1 ratio.
The spectrum of "passivity" ranges from truly hands-off (interest from a savings account) to semi-passive (managing a rental property with a property manager) to initially intensive but later passive (writing a book or creating an online course).
Realistic expectations are crucial. Most passive income streams require either significant capital (investing $500,000 at 4% yields $20,000 per year) or significant upfront effort (building a course might take 200+ hours before generating any revenue). The magic happens when you build multiple streams over time, each contributing a portion of your target income.
