fuzzy brain
imagine spending 3 days trying to grasp some fuzzy concept, finally wrapping your brain around it, and then someone else wraps her brain around it 30 seconds flat. while it's awe-inspiring to work in the company of other really smart/sharp people, it's also tiring up keeping up with them. which is why a 40 minute self pep talk on the drive to work is absolutely necessary to get through the day.
