How is Mukesh's attitude different from that of Saheb?

Mukesh's attitude was much different from that of Saheb. Mukesh was optimistic about a bright future unlike Saheb. Saheb lacked determination and had simple dreams. But Mukesh had a clear dream of becoming a motor mechanic and he was very determined to fulfill this dream. He was ready to face any hurdle that would come on his way, whereas Saheb made no efforts to achieve the things he wanted in life. In fact he gave up his freedom and dreams and took up a job at a tea stall.
