How can a young man rid himself of repeated private sins and achieve the sweetness of faith and the delight of obedience?

Among the things that help in abandoning sins are: knowing their danger, striving against the self by repeatedly repenting and not despairing, continuously supplicating to Allah and seeking refuge in Him, accompanying the righteous, acquiring Islamic knowledge, constantly reflecting on Allah's Names and Attributes, and on death and what comes after it, occupying oneself with what is beneficial, and staying away from the causes of disobedience.
