Perseverance and determination are some of the characteristics of a person who wants to be successful someday. You can't be on top of the hill without climbing it. Every sunset has sunrise which means in every challenge or trial in life, it comes with new beginnings and good results. Just like what the father did to make his children finish their study even though it's not that easy. He tried different jobs until he made his own business and until they became successful. He just learned how to cope up with different challenges and make that as a motivation to push through and be successful.
