If you want to expand your financial portfolio, you need to grow your financial literacy (via Medium). In other words, you need to keep learning. People who regularly read books and not just news articles are much more likely to achieve their goals than people who rely on YouTube videos for their information.

Learning new things with reading will help set you above your peers and make you a more desirable employee (via Medium).
