Lets say you were in an art school and you had to choose between teacher 1 or teacher 2, which teacher would you choose? And also, why?
Teacher 1 draws and paint really bad, but have ability to spot your flaws, your strong sides and see your progress. Teacher 1 are also able to tell you as you progress how and what to practice and focus on to improve as rapidly as possible in the direction you want.
Edit: Since I wrote in a way that could easily be misunderstood I now add this to teacher 1:Teacher 1 have been in an accident which injured him so that he/she no longer can draw with precision. Before the accident teacher 1 made the most amazing drawings and paintings that would make anyone drool.
Teacher 2 is the opposite draws and paint great but are really bad to communicate this knowledge to you. But teacher 2 will let you watch him/her draw and paint. Teacher 2 will also let you decide what he/she should draw if you ask.
