I think it can be useful to do something like this as a warm up before you draw for fun, especially if you are finding that you aren't enjoying drawing because you don't like your results. It can help you to relax more and have more acceptance for what you produce since you have no expectations going in for what you are about to draw.
If you want something to actually draw rather than just general mark making, I would recommend sketching more organic things like rocks and trees, where it is more forgiving if you make mistakes. Look for interesting rock formations or anything from nature where there is less precision involved.
