Here's a picture of the time I've spent so far studying the current course I'm on.
I'm not quite certain why I've chosen to represent the number of hours I've studied via the medium of pencils. It appeals to me to see a tangible representation of the effort I've put into something as amorphous as refining my mental toolkit. It's kinda pleasing to be able to 'see' it build up rather than just know it - think it's harder to become disheartened from doing something when you've got a way of seeing progress. Plus it gives me something to do with all the pencils I've got! £2 for 100 pencils? Bargain! :D
