Description: A three panel comic often referred to as "No take, only throw." The first panel is a dog biting a toy with the caption "I want to be good at my hobbies." The second panel is the dog looking angry and refusing to let go of the toy when a hand reaches out to throw it for the dog again, and it has the caption "No practice." The third panel is the dog, still angry and refusing to let go of the toy, with the caption "Only good."
I've seen it described as humans need some general ideas to feel like life has a point.
I've seen it broken down as autonomy (the feeling of driving your own destiny), mastery (the feeling of mastering a subject), and purpose (the feeling that what you're doing "means something").
Hobbies often fill the niche of "mastery" despite not improving our lives appreciably outwardly.
