Gang aft agley

You know the line that goes "The best laid schemes o' mice an' men..."? The continuation of it is "Gang aft agley".
I'm a 21st Century Aussie girl with no familiarity with the 18th century Scots language that Robert Burns was so eloquent with. Suffice it to say that 'gang aft agley', taken in isolation, is beyond my linguistic capabilities. I would probably guess "Go oft' ugly". However! In context I take a guess that it roughly means "often go pear-shaped" - which isn't too far off something going ugly.

That is a rough estimation of my plans for the 2 week break I had over the Christmas Period. I planned to be productive. I planned to work on new designs. I planned to be a shining example of industriousness. I was house sitting, so I thought that the fresh (quiet) environment would be helpful

Instead I managed to do a frightfully realistic impersonation of couch potato. There was an Xbox and a whole collection of DVDs - many of which I'd never seen. I did go swimming a couple of times, which was lovely... but hardly industrious.

It's a problem I often have when I'm having a holiday at home. I start off with great plans, but usually by the third day I'm reverting to "I'm chilling out" - formerly known as laziness. I'm looking forward to a weekend that isn't busy so I can spend some serious time at my workbench. I have some new designs I'd like to get cracking on, and some half-finished projects that are crying out for completion before the end of the month.
