This quote suggests​ that in the realm of manufacturing,‌ secrets or proprietary methods can be maintained for a longer period compared to those in trade. This is because manufacturing often involves complex processes, ​specific machinery, ⁣or unique skills that can’t be easily⁣ replicated or understood⁢ by⁤ outsiders.​ On the other hand,​ trade secrets usually involve strategies or information that⁤ can‍ be more easily ⁢discovered or replicated,‍ such as pricing strategies,⁢ supplier information, or client lists.

In the context of⁤ today’s world, this idea can be seen ⁣in the tech ‌industry. For example, a company like Apple can keep its manufacturing processes for its devices a secret for a⁤ longer time because they involve complex engineering and design principles. ​However, its trade‍ strategies, like its marketing approach or sales ​strategy, could be more easily replicated by competitors.

In terms of personal development, one⁤ could interpret this quote ⁣as ‍suggesting that the more complex and unique your skills or knowledge, the more⁤ valuable they are likely to be. This is because they are ⁣harder for others to replicate, giving you a competitive‌ advantage.⁣ Therefore, investing ‍time in developing unique skills or knowledge could be more beneficial in the long ⁣run.
