equilibrium
ee-kwuh-LIB-ree-um
/ˌiːkwɪˈlɪbriəm/
A state in which opposing forces or influences are balanced.
Often used in science (physics/chemistry), but in work-life balance, it refers to a mental or emotional state of stability.
The story behind the word. The word comes from the Latin 'aequus' (equal) and 'libra' (scales). This is the same 'libra' that gives us the zodiac sign and the abbreviation 'lb' for pounds. It literally means the scales are perfectly level.
