Some of the other folks there might be in the same boat you are, they are also your potential hires if you started your own company in the same area, so get to know them, figure out their strengths and weaknesses, what they are motivated by and what doesn't motivate them.
Talk to the managers and see what they are trying to get done (you mention they micro manage a lot) perhaps you can puzzle out what the group of them have been tasked to accomplish. If you like solving puzzles that can be entertaining for a while.
Look around for things that don't work well (are the printers always out of paper? Phones constantly ringing with no one answering?) see if you can engineer a way to solve one of those problems.
The bottom line is take ownership of challenging yourself to do something productive, don't wait for someone to either tell you what to do or "give you permission" to do that.
