If you are just starting a business or job, think about how you can create products. Most people start by offering services. This is still like a job that pays you money for time. You need to make products in order to be a truly independent entrepreneur.
Lawyers and accountants should create online courses based on their knowledge.
Writers should publish eBooks to get royalties while they sleep.
Designers should sell online art prints or branded merchandise.
Marketers should sell guides on best practices for growing a business.
Even if you have a job, you should be able to come up with a product to replace yourself. Then you can sell it anywhere and scale yourself to success.
