Back it up
If you are not storing your jokes on the computer, you probably will. It is the best insurance you have from losing them. And if you are storing your jokes on the computer, remember to back-up. I would recommend backing up at least once a month at a minimum. I also believe that today we exist in two world simultaneously - the real world and the digital world. And so I recommend that you back up in both worlds as well. For example, if you have jokes written in your notepad, put them on your computer in case you lose your notepad. And if you have jokes on your computer, print them out in case you lose your computer. The same applies to photographs, important documents and so on. Back up in both worlds so you never have to worry about either.
