Different Life Stages Emphasize Different Goals
Before turning 21, invest in your growth: work hard, learn a wide range of skills, and prepare yourself for life in the real world.
From 21 to 60 is your golden window. Make the most of your working years by sharpening your professional skills and pushing toward the top in your field, earning well while keeping spending in check. Let the water in your "wealth reservoir" keep rising. If you want to avoid a midlife or even old-age crisis, build on that foundation by actively expanding your passive income streams—exploring new sources beyond your salary and establishing your own paths to wealth.
By retirement, when you no longer need to work, your "wealth reservoir" should still be feeding you a steady flow of income. You don't have to work to keep earning, your cash flow stays robust, you're shielded from sudden crises, and your overall happiness improves.
That's probably the simplest and clearest roadmap for life
It's also worth taking the time to write out a will and keep a list of your account passwords somewhere accessible—just in case something happens, being prepared is better than leaving everyone scrambling.
