When you get off the Mass Pike take 128 North, which you have done every day for the last year, as opposed to taking 128 South, which you never do - expect for today.
Why? Well, first of all, it is the wrong way. Second, 128 is not fun. I don't know if other states allow this, but one can actually drive in the break down lane on this road during the morning and evening commute.
If you do commit the same mistake tomorrow, make sure that after you get off 128 South, you don't take the first ramp you see (again) and get right back on - you guessed it - 128 South. It's still the wrong direction.
When you finally right yourself, pay attention to where your exit is, especially now that you are coming at it from the opposite direction. Don't go past it like you did this morning.
If and when you finally arrive at work, give yourself a big pat on the back. And a coffee.
