A pretty nice early, little-known film by the most internationally famous Uzbek animation director, Tulyahodzhayev. Serious and philosophical, with very nice drawings. The animation seems like it uses only key frames and no in-betweens, unfortunately -- the team was tiny, with only one animator, and I suppose it was decided to focus on detailed drawings over smooth motion.
The only dialogue are some important lines of poetry at the beginning and end. I could not make the translation rhyme, but I did try to keep it close in meaning and have the same number of syllables.
My interpretation of the three challenges is that the first is "romantic pursuit", the second is "career" (or something like it), and the third is a "midlife crisis", e.g. buying a sports car to try and bring back your youth.
