I've never been completely DIY but I had somebody teach me how to be semi-DIY (Yes I know that sounds stupid) a few months ago. It was almost like getting in a time machine and going back to pre-Grand Exchange RS, back then I had a lot more fun playing for whatever reason. A lot of it is just nostalgia for me.
