Life hacking refers to any trick, shortcut, skill, or novelty method that increases productivity and efficiency, in all walks of life. It is arguably a modern appropriation of a gordian knot — in other words, anything that solves an everyday problem in an inspired, ingenious manner.

For me, the key ideas are:

• solves [a] problem: a lifehack must be about solving a concrete problem. It's a “how” question, not a “what” or “why” question.
• an everyday problem: a lifehack concerns everyday life. Problems encountered as part of professional life, or requiring specialized knowledge, are not lifehacks.
• increases productivity or efficiency: a lifehack is about solving the problem quickly and with few resources, not about finding the solution that produces a high-quality result.
• trick, shortcut, skill, or novelty: a lifehack can involve taking shortcuts. It doesn't have to be robust or generalizable. It doesn't need to have been covered in peer-reviewed literature: something made up on the spot is fine as long as it works.
