In the same way a picture can be worth a thousand words, a small few words can be worth the same. There’s an ocean of words out there, and it’s easy to drown in them. Meanings can get lost in all the redundancies, re-phrasing, and circular reasoning.
The purpose of words is to translate to thoughts, feelings, and ideas, and short quotes and sayings can be the best way to get the point across. It only takes a small spark for inspiration to strike.
