A recent article in Entrepreneur highlighted serial entrepreneur and top booked business speaker Kevin O’Leary‘s financial know-how. Building off of the financial advice for achieving millionaire status he shared Monday on X, the piece pinpoints his two major strategies for folks to be smart with their money.

First and foremost, he encourages that people invest a set amount of each paycheck, or even better, any money that comes into their hands at all; for younger folks, that could even mean birthday money from grandma. He suggest 15% as a solid benchmark one that would allow even a person with a yearly salary of $65K to have millions in saving.

O’Leary couples this with the advice that people must avoid wasteful spending– overpriced coffees and sandwiches add up.
