This means that whatever career or job one has, however simple or modest, it can be made more dignified by behaving in a good- tempered and cheerful manner and with kindliness towards the people one comes in contact with. For example, even a simple job like that of a security guard at a mall can be made pleasant and dignified if the guard smiles and says ‘Thank you’ or ‘Good morning’ every time he/she checks a person.
A sweeper’s job can also be made more dignified if he/she just nods and smiles at passers-by or helps them if they are in need.
