I've always been a drawer. But I realize now how long it's been (since the summer, I believe) since I've actually sat down with my sketch book and observed a picture or subject long enough to record them through my perspective. I remember how good it belt to finally complete a drawing and be proud of it.
(I know, my signature sucks)
I used an old novel as a sketch book for a while when I lost my main one.
A drawing I did on the back of a paper placemat waiting for my meal :)
