sketch project

I started a new sketchbook that I'm trying to get done withing a month. I'm going to be posting bits and pieces of this undertaking on my instagram page but I don't want to separate deviantart as some kind of gallery for my "fancy" art because that attitude is kinda harmful for me and makes me frankly scared to post anything at all. 

Besides sketching is fun. This one is a plan for a commission I'm doing currently. It's going to be a mad dash to get all this art done between everything else but I'm kind of also trying to create a scenario where I'll be forced to do bad sketches and will just have to be okay with that happening. I've quit so many sketchbooks because the successful drawings made me feel unworthy to touch the pages again  

Am I the only one who has problem with sketchbooks? Please let me know if there's any tips that you have found useful in the completion of these things.
