There is a very important lesson taught by the Rabbis about the nature of things. The Rabbis say the following: לא יגעתי ומצאתי אל תאמין. יגעתי ומצאתי, תאמין.
If one claims that he achieved something of significance, with no effort, don’t believe him. But if one says that he accomplished with great effort, believe him.
The point of the Rabbis is that anything worthwhile has to come with hard work and diligence. If something comes easy, it will probably not last.
This is true of our Torah study and Mitzva observance, as well as how hard we work in our marriages, our jobs, parenting, and being a trusted friend. There is no substitute for due diligence and hard work.
