うちに (uchini) - while; during; as

--- Notes ---
うち　（内） means inside. so this is 'inside the time' or while.

I found this helpful:
うちに indicates a period of time WITHIN WHICH an action occurs, and
corresposnds to English 'while still', or in negative constructions
'before'.

It is different to あいだ, which indicates a period DURING OR THROUGHOUT
WHICH an action occurs, and is equivalent to English 'while'.

学生のうちに、よく勉強ひておきなさい。
Study hard while you are still a student.

Different to:
学生の間に、いろんな所を、旅行するつもりです。　I
plan to travel to lots of places during the time I am a student.

うちに is also used to indicate an event building up or reaching a
climax AS some action is being done.
