1) Be discerning where your personal appearance, conduct, and who you spend time with outside of work (or obligatory family functions) are concerned.
2) In other words, be meticulous when it comes to the details of your work and casual attire, your behavior in public, at home, and by yourself as well as in your choice of friends.
