One interpretation of the image and caption is that it reinforces how some folks perceive the progression from novice to expert:
Stage 1: You suck.
Stage 2: You're an expert.
In fact, mastering a skill involves hundreds of stages of incremental improvement over a very long period of time.
I believe a key reason so many people on the road to mastery call it quits is not because drawing a beautiful owl in pencil is superhumanly hard. It's because they thought it would be easy.
Another interpretation of the image is that it's showing that step one is always "start," and step two is always "keep going and going and going until you've nailed it."
