10. You Don't Feel Free
You feel chained to your desk and you're gutted at the fact that you're now a grown up and you have a mortgage because if you didn't have any responsibilities, you'd be happy to just walk out of that door forever. Unfortunately you have a wife and two kids, or a house to pay for, or credit card bills from your happy life at the weekends. So walking out isn't an option, which sort of makes you resent the happy version of yourself who goes home and spends all of the money on loved ones. Idiot.
