1. Develop an Entrepreneurial Mindset Early

As a young adult, Buffett had a knack for thinking outside the box and finding creative ways to earn a buck. He had a job delivering newspapers and a pinball machine business. So, learn from Buffett: If you want to become a millionaire, don’t put off business until you’re older. Look for ways to make more money — and once you earn it, come up with a savings plan and start investing.

People who invest early in life save more and get the benefits of compounding interest, said Joshua Wilson, a Fort Worth, Texas-based partner and chief investment officer with WorthPointe Wealth Management.

“People who start early also tend to become more financially conscious in other areas,” he said. “They tend to notice areas of waste sooner, and find ways to apply investing wisdom to other parts of their lives.”
