Understanding the Numbers
Turning 30 feels like a milestone because it is one. Research by psychologist Meg Jay, author of "The Defining Decade," shows that 80% of life's most defining moments happen by age 35. Your twenties aren't a throwaway decade — they're when you build the foundation for everything that follows.
If you're 25, you have about 261 weeks until 30. That sounds like a lot, but consider: many of those weeks will be routine. The question is how many of them will be intentional. What skills will you build? What relationships will you invest in? What experiences will you prioritize?
The "30 before 30" bucket list is a popular framework for this exact reason. It takes the abstract anxiety of approaching 30 and channels it into concrete goals. But instead of 30 items, consider using weeks: what do you want to accomplish in the next 100 weeks? The next 50?
Neuroscience tells us that the brain's prefrontal cortex doesn't fully mature until around age 25. This means that if you're in your mid-to-late twenties, you're at the intersection of peak cognitive ability and enough life experience to make good decisions. It's a powerful combination — use it.
