"سه اصل اساسی برای دستیابی به هر چیز با ارزشی عبارتند از: کار سخت، پشتکار، و عقل سلیم."

The essence of the quote is simple: to achieve anything truly valuable in life, you need three things—hard work, perseverance, and good judgment. Let's break that down a bit.

First off, hard work is pretty self-explanatory. It's about putting in the effort, the sweat, and the hours to get something done. Think about athletes training for the Olympics. They spend countless hours every day working out, honing their skills, and pushing their bodies to the limit. It’s not just talent; it’s the relentless grind that sets them apart.

Stick-to-itiveness—now there's a word you don't hear every day. It means not giving up, even when things get tough. We've all been there, right? Staring at a seemingly insurmountable challenge and wanting to bail. But the ones who push through, who keep at it despite setbacks, are the ones who eventually see success. J.K. Rowling, for example, faced numerous rejections before “Harry Potter” became a global phenomenon. What if she had given up after the first, or even the tenth rejection letter?

And then there's common sense. This is about making smart decisions and not overcomplicating things. It's knowing when to take a risk and when to play it safe, understanding people, and seeing things clearly. You could be the hardest worker and the most persistent person out there, but if you're making foolish decisions, all that effort might go to waste. Think about Warren Buffet, who has always emphasized the importance of making sensible, well-informed decisions in his investments.

So, how do we apply this wisdom in our lives? Let’s say you want to start your own business. It’s not enough to just have a great idea. You’re going to need to put in a lot of hours to get it up and running—hard work. There will be moments when you're facing financial difficulties, or when things just aren't going according to plan. That's where perseverance comes in. And then, of course, you need to use your common sense to make smart business decisions, like managing your budget wisely and understanding your customer base.

Here's a relatable story to drive it home. Imagine you're a university student. You’ve got a big exam coming up and it's on a subject that’s not your strong suit. The easy route would be to throw in the towel and accept a mediocre grade. But instead, you decide to put in the hard work. You spend extra hours in the library, attend study groups, and maybe even get a tutor. As the exam approaches, you’re stressed and tempted to give up—stick-to-itiveness kicks in here. You push through those late-night study sessions and keep at it. On the exam day, you apply common sense by reading questions carefully and managing your time well. In the end, you not only pass but do better than you ever thought possible.

So, next time you’re tackling a goal, remember: work hard, don’t give up, and use your head. It’s a recipe for success that’s stood the test of time. And hey, if you ever feel like you're faltering, just think of all those who have been in your shoes and come out on top, not because they were the smartest or the most talented, but because they had the right mix of these three essentials.
