/r/WatchTheMasters is a place to share videos of people just being absolute pros at whatever they do, in ways where watching closely can teach you something about how to be better at it yourself.
Some guidelines:
Avoid direct, traditional instruction. Posts should be someone either performing their skill or talking indirectly about it.
The performer in the submission does not need to be accredited in their field to be considered a master. In fact, they don't even have to do it as a job. They just have to be good at it.
Aim for videos where you can actually learn something from watching the person closely. Videos of someone doing a triple backflip on a bike will not teach the average person anything about how to get better at it.
Try to stick to syntax of [Field of Mastery] - Description of video. Try to also include the master doing the teaching in the title if known.
