did anyone chop their hair off?

I have a hair appt Tuesday and part of me wants a trim and let it keep going-part of me wants to cut it short so the time it takes to wash, dry and style will be super fast and easy. 

Did anyone make a big change to their hair and regret it or was it a good decision?

(My hair is between my chin and shoulders now so it's not like a huge chop off it I go shorter)
