The extremely heavy and hard work that Gary faced in the fields where he worked, made him highly value the effort and determination of people and especially his own.
Explanation:
I believe your question refers to the book "One last time" where Gary Soto presents his family's life as refugees. During his youth experiences, Gary had to work in the fields of grape plantations, together with his mother. The work was very difficult, extremely tiring and had a very low remuneration, but both Gary and his mother knew that this work was necessary and for that reason they dedicated themselves a lot and struggled to do the best they could. This influenced Gary's attitudes towards work, as he realized that determination and effort are the necessary feelings in any activity that is done, even if this is a bad and very tiring activity.
