Final answer:
The saying 'You reap what you sow' in school and life means that the effort you invest results in corresponding outcomes, emphasizing personal responsibility for success and failure.
Step-by-step explanation:
The saying "You reap what you sow" signifies that in school and life, the efforts and decisions you make have a direct impact on your future outcomes. If you exert hard work and diligence in your studies, you can expect positive academic achievements and valuable skill development that may lead to better future opportunities. Conversely, neglecting your studies or responsibilities can result in negative consequences, hindering your progress both academically and professionally. This principle emphasizes that success and failure are often the result of personal effort rather than external factors. The fulfillment of one's education being linked to social class further illustrates that despite challenges, the effort one puts into overcoming these obstacles can lead to self-improvement and perhaps a change in one's circumstances over time.
