Reward & pleasure
When dopamine levels are high, you may experience more pleasure from activities and are more likely to feel the reward after completing a task [2].

Increased dopamine levels have also been linked to motivation and alertness [3,4]. A study found that in the brains of highly motivated individuals, there was an increased release of dopamine in the areas that involve reward and motivation [5].
