Becoming rich and staying rich

Creating something of value is the most effective way to become rich.

Diversification is the most effective way to stay rich.

Running a small business instead of a startup is preferable for the majority

Dear politicians & bureaucrats, please don't advise every youngster to start their own startup right away. Startups are the Olympics of doing business. Super-majority of founders, especially those with mediocre skills, poor work experience and poor discipline, will fail. 

Most of these amateur founders and their misinformed families are ill-prepared for their failure in running startups, and hence will suffer. Running startups is not for everyone.

Instead, be realistic and suggest to people with average skills to start small businesses instead of startups. At the same time, make people aware of the benefits, challenges and risks of running startups so that those who want to run startups can make educated choices.
