The idiom "Heaven rewards diligence" means that God will reward everyone according to their diligence. More hard work, more harvest, as long as you pay enough efforts, you will definitely get the corresponding harvest in the future. As the saying goes, "Opportunities are reserved for those who are prepared". Only by working hard can we seize the opportunity. Because things are unpredictable, you may not succeed if you work hard, and you will definitely not succeed if you don't work hard.
