A chip on your shoulder can be fuel or dead weight. Depends on whether you burn it or just carry it.

Resentment can be converted into effort, and it can also just be hauled around. The difference is whether it turns into work or into commentary, and the second is heavy and produces nothing. Fuel gets used up, while weight does not. Both feel similar while you hold them, which is how people confuse the two for years.

Ask whether the thing you are angry about is currently producing training, practice or output. If it is, keep an eye on what it costs you. If it is not, stop rehearsing it, because it is charging rent and paying none.
