Word that means "flying" but in the sense of "growing" and "not to give up" and "be free"


I was looking for a word in Japanese that means "flying"/"fly" but I wanted it
to be a metaphor for "growing" and "not giving up" and "be free". Something
along those lines. Since Japanese has so many words for the same concept (I am
almost a total noob in Japanese) I am kinda lost.




I consider the word 巣立つ (すｰだ-つ) quit fitting. 巣 means "nest", and 立つ stands
for "stand" (HA!). It literally means the little birds grow up and flew away,
and is used to say that "the youngs grew, and now are away from the elders
grasp", or "became independent" in short.
