Except the "paint drip" aspect of this successful person might be entirely irrelevant to their success. Imagine if Keith ate oatmeal every day for breakfast, and there was an "Oatmeal people" article describing why eating oatmeal for breakfast is the key to Ken's success. After all, it gives him long lasting energy, having a routine can be useful, it is simple to prepare and you can think about other things while making it, etc.

Or, for every "paint drip person", you might find another person who is equally as successful and devoted their entire energy to a single project or idea.
