Dont.........

Don’t leave people wondering how they’re doing; tell them.

Don't think that people know how they're doing: tell them.
 

Don't assume that your saying nothing means everything's OK; tell them.
 

Don't let people worry when they hear nothing from you: tell them.
 

Don't let people go to extreme lengths to find out how they're doing: tell them.

Don't assume they care, make sure they do

Don't sit back and let people walk over you, because they will 

Don't forget to speak your mind, they might hate you for it, but atleast they will know what you were thinking
