Focus on building multiple income streams
Even if you have a steady job, do not allow yourself to become complacent. Maximize your income while you can from multiple income streams, which will act like a moat when challenges occur in your job or otherwise. Do an assessment of your skills, and consider starting your own small side business, while you continue to do your job.
Numerous online business opportunities are available today, which involve minimal capital and can generate a reasonable amount of income. If you are good at stock investing, or feel comfortable with mutual fund investments, you could gradually build a substantial passive income in the form of stock dividends.
