I am looking for my drawing portfolio, and I can’t find it anywhere… Does anyone know where it is?

I am restarting to draw, so digging up what I used to draw and revisiting where I used to be. Some sketchbook from my more creative days (grad schools till the first 4 years of my career) contains a lot of pictures and interesting ideas.

Where had I been in the past 5 years? I think I had been completely lost and had been wondering around a dry desert.
