I'm looking for a synonym (single-word or short phrase) for the word lifehack. I read Wikipedia article, and checked few online dictionaries. I could not find any synonym. The word is informal and it means:
A strategy or technique adopted in order to manage one’s time and daily activities in a more efficient way
I understand that the word origin is by extension from the computing sense of hack, meaning to manipulate a computer program in a skilful and often creative manner . The word was coined in 2004.
If there is no other current synonym, how native speakers used to refer to the meaning above, before 2004?
lifehack, or short phrase I can use to refer to the same meaning. It does not matter whether formal or informal, modern or classic.
