I feel that bold letters will represent me because I like to be different and stand out and not do what everyone else is doing. I also will use serif because I like to be fancy sometimes. Things like color contrast and size contrast will represent me professionally. I would use color contrast to let my viewer understand what the purpose is and for size contrast I would use this to also let the viewer know what the purpose is and what I want them remember after reading what I created. I will also use emphasis in my text for the same reason.
