A trick for Rough work

I use a lot of my notebooks and registers and write a lot of rough notes at the back pages while I am thinking or practicing.

The one problem I was faced was with how to jot down longer notes, like programs, derivations or simply anything that ran much longer than a page, because then I'd be forced to write stuff in reverse order (E.g - begin on page 320, then goto page 319 when I run out of space, etc).

So a simple way to write rough notes would be to start upside down.

Instead of writing in the usual fashion, rotate your register/notebook by 180^o.

This has the advantage that you can continue to the next page, which is actually the previous page on your notebook, but still maintain readability.
