The key to a long and happy life is Routine.
If you're used to getting up at 5 in the morning, don't get up at 4:50 or 5:10. If you shower before you brush your teeth, don't change the order one iota. If you put your socks on first and then your pants, do it like that for now and ever more. If you have coffee and cereal before going to work, don't have a banana and juice.
Routine is the key.
This morning I got up late. I forgot to brush my teeth. I'm not sure if I'm wearing underwear. I forgot to bring my coffee cup to work so I could have my morning cup of "get up and go." And I have no idea where my cellphone is so I can call up my wife and complain about the whole thing.
Mine's out the window.
I probably won't survive the day.
