Backup.

For all digital storage tools you have, you'd definitely be thankful if you had done backup.
Likewise for one's HP but backing up this thing very leh chey, it's like doing those super boring data entry job. I reached the 'M' section of my phonebook and my eyes feel strained. I quit.

HJ gave a good idea for walls. ' do ZEN '.
I'd love to put this up on my wall.
Just imagine 禅 against an olive green background with a thick black circle around it.
