Quick and easy answer for that one Gilbert!
go out into the garden, choose the furthest away bit of your lawn and the back door that you can, and dig a hole about 3 inches across and perfectly round.
Insert an empty baked bean tin, make good the holes around the tin, then go back and use it as a practice hold to get some time in on your short game.
After doing that all afternoon, you will have reminded yourself of the total frustration it is known as golf, part of which includes booking yourself in on the wrong day!
Simples!
