As someone who tried to draw once upon a time but gave up because I was terrible at it, I don’t exactly lack in respect for artists. To draw down to every detail — whether doing so realistically or not — is fucking hard. But I was ignorant about the actual start-to-finish process of creating even one manga page (and probably still am, since I doubt this episode covers everything); this shit is ridiculous. Then again, doing anything at a high level takes a truckload of work, so with that in mind, it’s not especially surprising to see that even one drawing on a single page takes a lot of patience to see through.
Have to say it’s also cool to see Mashiro and Takagi be practical and hard-working about this even though they’re utter goofballs with just about every other aspect of their lives. The “pride/arrogance, effort and luck” bit especially strikes me as valuable for them to know. Obviously you have to believe in yourself to succeed; if you go into something expecting to fail, then you set yourself closer to failure. And effort is a big “duh” too. If you’re talented enough, you can probably coast on your skill for a while, but eventually a wall is going to come, and the more you coast, the harder that hit will be.
Luck, though . . . Takagi is skeptical about that aspect, but I think it’s because he is viewing it the wrong way. While I’m a believer that people make their own luck (by being flexible enough to adapt to unexpected circumstances, for example), I also believe that is true only to an extent. There are many circumstances and conditions that either aid or hinder people (age, economic condition, location, etc.) that are simply out of people’s control. Certain people exist in better conditions for success in certain areas, and they achieve success by having the foresight to see their advantages and push them as far as possible. That might not be exactly what Mashiro means by “luck”, but I think that’s how it best applies to their situation — if an advantage falls their way, they have to be ready to use it.
