The TV show Heroes had a character, Hiro Nakamura, who could teleport in time and space. To do so he had to concentrate awsomely. Actor Masi Oka portrayed this with wonderful physicality (part of a superb performance, which made the earnest yet puppyish Hiro a treat to watch). It looks as if he is trying some barely manageable feat of strength or stamina.
It reminded me of something. As an inexperienced project manager I would sometimes try to force my projects along by sheer willpower. It doesn't work of course - once you are relying on others to do parts of the work rather than doing it personally, you lose the option of advancing things by, say, personally working late. So there are times when the project is temporarily beyond your control because you're up to date with your contribution and the rest of the team are working on theirs with all reasonable speed and care. It took me a while to get used to using the time to work on something else, instead of straining Hiro-like to teleport my project closer to its goals. I never did achieve teleportation or time travel, it just made me tired.
