To reach happiness, a person should try to become a perfect man, with high manners like our Prophet ﷺ; beloved one of Allāh ﷻ. Those that respect the Prophet ﷺ, and aspire to be like him ﷺ will be given from his ﷺ attributes. The Prophet ﷺ is perfect but we are human beings and make many mistakes. But we must move slowly towards perfection, and do good. When we do good, often others will do wrong to us. But we should forgive those ones. It is not easy, but difficult things have greater virtues. You can kill your ego and strengthen your spirituality through forgiveness.
