I think it is wonderful when people have hobbies and passions. I dmire those who collect various things. I wouldn't have the patience. My hobby is watching films, reading books and I like meeting friends. Unfortunately, nowadays I am very busy because I have to study for my matura exams.
Can you imagine that my student, now 17 yo, started earning money from his hobby? He paints figures for RPG fantasy games fans. He has a website which brings him customers. And the word of mouth also works. He is able to make about 100 zlotys per night - one figure costs ab. 2.5$ and complex ones 10$.
