efficiency and effectiveness

Efficiency is about doing things in the right way — using the least amount of resources (time, money, effort) to achieve a goal. Effectiveness, on the other hand, is about doing the right things — focusing on activities that lead to the desired outcome. For example, being efficient means completing a task quickly with minimal waste, while being effective means ensuring the task actually contributes meaningfully to your overall objectives. Both are important: efficiency maximizes resource use, and effectiveness ensures you’re achieving the right results.
