"associate yourself with men of good quality if you esteem your own reputation for tis better to be alone than in bad company" I think it means that to hangout with people like you . And to hangout with people who are good people and who will accept you for who you are because if you dont your going to be lonely and have no friends. It is better to have none then to bad and choose the right. Sometimes you will walk through fake friends that will put you down and bully you but just ignore them and dont hangout with them anymore because they arnt true friends. Choose friends who are ctr people because those are the freinds who will accept you and be there for you and love you they are not fake. Dont hangout out with someone your not and dont smoke or be bad they will just force you and then soon your going to be like them and you will not be a ctr person
