Sitting in the company of poor people helps us to get onto right track and enables us to ponder on blessings we have, seeing people who are deprived of basic accessorizes of life, not only softens our hearts, but makes us humble, and thankful to our creator. That is why it has been told to us to always see people below us, and not to fall into unremitting worldly race, because it never ends.
Some of what we do is greater than other things depending on where Allah made us excel. It is like a farmer who is producing exotic fruits and he has some trees which are special which he reserves for himself and does not take to the market while some are standard marketable produce and others are below par than what he would want to send to market. Allah grants us special blessings in some areas and makes us deficient in others.
