Why Your Career Is a Marathon, Not a Sprint: The Surprising Truths from The Long View

Unlock the secrets to a fulfilling work life by thinking decades ahead.

Imagine you’re running a race, but the finish line is so far away you can barely see it. For most of us, that’s what our careers actually look like. In The Long View, Brian Fetherstonhaugh argues that the old way of thinking about work—climb fast, retire early, and ‘make it’ by 40—no longer fits reality. Today, careers last 45 years or more. That’s more time after 40 than before it, and it means the strategies that work for a sprint can leave you exhausted, unfulfilled, or, worse, obsolete just when you should be hitting your stride.

So what does a marathon mindset look like? It starts with understanding that careers have three distinct stages: Start Strong, Reach High, and Go Far. Each lasts about 15 years and demands a different approach. In the early years, your job isn’t to find the perfect role but to explore, experiment, and build foundational skills. You’re gathering ‘career fuel’—skills, experiences, and relationships that will last a lifetime.



Mid-career, it’s time to specialize. This is when you find your ‘sweet spot’—where your strengths, passions, and what the market values all intersect. It’s also when you start to build your personal brand and reputation. Deliberate practice, feedback, and mastery become your tools for standing out. And as you move into the later years, the focus shifts from personal achievement to legacy. Mentoring others, staying relevant, and reinventing yourself keep the journey meaningful and fresh.

What’s truly surprising is how much of your wealth, influence, and satisfaction comes in the second half of your career. According to Fetherstonhaugh, 85-90% of personal wealth is accumulated after age 40. The relationships and habits you build early on pay off in ways you can’t imagine when you’re just starting out.

But longevity brings new challenges: burnout, irrelevance, and the risk of plateauing. The Long View offers practical tools to help you take stock—like ‘career math’ to see how many years you have left, annual value scores to measure satisfaction, and time portfolio audits to ensure you’re investing in family, learning, and wellness, not just work.

Takeaway: The marathon mindset isn’t just about endurance—it’s about pacing yourself, reinventing as you go, and finding meaning at every stage. If you want a career that’s not only long but also rich and rewarding, it’s time to start thinking decades ahead.
