Power levelling

Power levelling or grinding, is the term used when a player is trying to raise their level in a certain skill in as short a time as possible, without worrying about making a loss or gaining other resources. This may involve using almost every possible resource available, making up for the loss when the target level has been achieved.

A good example is when a player trains Mining, dropping ores instead of banking or selling them. This saves travelling time, which makes levelling faster, but no monetary profit is gained. Gaining a cash pile from training won't matter during power-levelling, because your main goal is the fastest experience possible.
