"プランBを持つ必要はない、なぜならそれはプランAから気を散らすからだ。"

The essence of the quote is simple: when you're focused on your main goal, don’t let distractions or backup plans pull you away from it. If you keep a safety net, you might be less committed to making your primary plan work. This idea suggests that focusing all your efforts and energy on one goal increases your chances of succeeding.

Now, why was this said? Who came up with this notion? This saying has been associated with several successful people—like Will Smith, who emphasized the importance of unwavering dedication to a single goal. The idea dates back even further, though. Think of historical conquerors like Hernán Cortés, who famously burned his ships upon arriving in the New World, leaving no option for retreat. His men had no choice but to succeed—and they did. The core message: when there’s no way out, we often find a way through.

Let’s dive into a real-life example. Imagine you’re a young entrepreneur with a brilliant idea for a startup. You believe in it with every fiber of your being. But, fearing failure, you keep your day job and only work on your startup in your spare time. While that may seem prudent, it splits your focus. Your attention is divided. You’re less likely to give your startup the energy, time, and creativity it needs to thrive. Instead of going all-in on your plan A, you’re hedging your bets.

Now, let’s talk practical advice. If you’ve got a passion project or a big goal, dive in headfirst. Commit fully. This doesn’t mean being reckless—do your homework, plan meticulously, and prepare for challenges. But once you’ve decided, give it your all. Remove the distractions. Let your plan A be the only plan. It’s like trying to swim while holding onto a lifeboat; you’ll never put all your effort into swimming if you know you can just hop on the boat.

Picture this: You’re an aspiring writer, dreaming of publishing your novel. You've got a decent job that pays the bills but leaves you feeling unfulfilled. Every evening, you promise yourself to write a chapter, but the safety of your job means you never quite feel the urgency. Now, imagine quitting that job (risky, I know). Suddenly, your writing isn’t just a dream—it’s your lifeline. You pour your heart into it, working harder than you ever thought possible. With no plan B, your plan A becomes everything. And through that intense focus, you create something extraordinary.

In essence, this quote reminds us to put all our eggs in one basket—and then watch that basket very closely. It encourages us to channel all our energy into what truly matters to us, without the temptation of a fallback option. So next time you’re dreaming big, think of Cortés burning his ships, or that writer who finally penned their novel when there was no other option. Dive into your dreams, and don’t look back. And hey, maybe next time we chat over coffee, you’ll share your own success story of how plan A worked because you didn’t let plan B get in the way.
