"朋友们在季度收益公告后祝贺我，说：“干得好，这个季度很棒。”我会说：“谢谢，但那个季度是三年前就定下的。”"

Simplified Meaning:

When someone says "Good job, great quarter," the speaker is pointing out that the success we see now was actually planned and worked on years before it happened. Think of it like planting a tree. You might admire a tall, healthy tree now, but it actually started as a small seed that someone planted a long time ago. They watered it, gave it sunlight, and protected it from harm, and over time, it grew into the strong tree you see today. In a business context, this means that the achievements and profits reported this quarter are the result of decisions and actions taken years ago. The positive results are because of long-term planning and consistent hard work, not just recent efforts. To apply this idea in life, remember that big successes usually require patience, early preparation, and persistent effort over time. For example, if you want to be good at playing the guitar, you need to practice regularly for years. The impressive performance that others will see someday is actually the result of all those hours of practice you put in way before. So, when working towards a goal, keep in mind that it may take time to see the results.
