How does one Idolize His Lower-Self?

A person who idolizes his own lower self is a person who holds his own self-interests and comfort above the interests of the religion. However, a true and sincere believer only believes in Allah and acts in a manner that will please only Him. This is valid for every condition. Such a person never compromises from the interests of the religion nor from the limits of Allah, even when he gets sick, faces difficulties or his interests are facing ruin. However, if a person cannot make self-sacrifice for matters that seem to be small, and instead chooses what seems attractive to his inner self by abandoning the morality of religion, then this person is only trying to please his own inner self and thus has come to idolize it. Allah reveals in the Qur'an as follows about those who idolize their inner selves:
 

Have you seen him who takes his whims and desires to be his god–whom Allah has misguided knowingly, sealing up his hearing and his heart and placing a blindfold over his eyes? Who then will guide him after Allah? So will you not pay heed? (Surat al-Jathiyya, 23)
