One way is to make list's!
Then 'try' when you can to knock out those things on the list's.
You can make a list of things to do around the home, that you may have forgotten to even consider.
Make another list of what you would like to do in the next 12 months, that is a project of some kind....then list what you need, & how much money, and how long it will take you.
Try to write a poem....to someone very special in your life.
Keep your mind active, by spending at least some of that dead time.....that challenges your brain...word puzzles.
Write a list also, of Christmas gifts for this year....and what you think that person may like.
Finally, just read a book!....very relaxing.
