I'm sure everyones found their own way to write a journal, but thought I'd share mine as it might be helpful!
I'm using Microsoft Office OneNote... It's a program that I uploaded to my laptop to get Word, excel etc. It's brilliant, I discovered it whilst doing a project at college and its great bacause you open the page, can click anywhere and start typing. It automatically saves and uses boxes, which you can always add too, but I like that they can be anywhere on the page. You can add loads of different tabs for differnent thought paths, and also link internet addresses and photos... It basically turns into a massive scrap book of your thoughts, things that you've stumbled apon and research! I'd highly recomend it, it's great to have everything in one place!
Hope that explaination is understanable!! :)
