A skill is the ability to carry out a task with pre-determined results often within a given amount of time, energy, or both. Skills can often be divided into domain <nowiki/>general and domain-specific skills. For example, in the domain of work, some general skills would include time management, teamwork and leadership, self-motivation and others, whereas domain-specific skills would be useful only for a certain job. Skill usually requires certain environmental stimuli and situations to assess the level of skill being shown and used.
