Make sure the first thing you do in the morning is making your bed, so that by the time you get to the nighttime and it’s time to get into bed, the bed is nice to get into (making your bed as soon as you get up also puts you in the right frame of mind for the day ahead, as you’ve already ticked off job #1)
Don’t put off jobs that need doing, otherwise they’ll be on your mind at night in bed - get a To-Do list and get the jobs done, pay your debts, apologise to the missus, clear your conscience…
