It's more convenient for me to shower in the morning and half ass the hair dryer because I drive with the windows down whereas when I shower at night I have to dry it completely because it lays weird if I go to bed with it wet. But I shower at night anyway because I can not motivate myself to do anything so early in the morning. If I try I'm just like "...whatever I'll just sleep in and go to work gross looking...not worth it."
