Which two factors caused Soddhartha gautama to give up his riches and leave his home

Even though he was a wealthy prince and his father gave him every material thing he could ever want or he felt there was more. One day he left his home to go out and meet the people. His father had hid human suffering from him and he was finally seeing it. He saw an old man and sick and suffering people. These factors cause him to give up his riches and home to strive to end sickness, aging, and death. Thus, he began living his life as an ascetic.
