Hypomania is best described as:

Hypomania is best characterized as a state of manic behavior without significant functional impairment. In this condition, individuals often exhibit elevated mood, increased energy levels, and heightened creativity compared to their usual state. However, unlike full-blown mania, hypomania does not lead to the extreme difficulties in functioning that can be seen in manic episodes, such as impaired judgment or inability to maintain daily responsibilities.

Individuals experiencing hypomania might still be able to carry out their normal routines and responsibilities, albeit with more energy and enthusiasm than usual. This differentiates hypomania from other mood disorders. For example, deep depression involves a pervasive low mood and lack of motivation, severe mood swings indicate rapid changes between emotional states rather than a consistent elevated mood, and extended periods of normal mood do not capture the essence of hypomania, which is specifically marked by the elevated and energetic state without the debilitating consequences of a full manic episode.
