A "creature of habit" is someone who tends to repeat their behavior or routine regularly. The term "creature of habit" can have a negative connotation, implying someone who is unwilling or unable to embrace change or try new things. However, there are several alternative expressions that convey similar meanings without carrying the same negative weight. For instance, one may use phrases such as "routine-oriented," "consistently predictable," "unwavering in their ways," or "steadfast in their habits." These terms, while still conveying the idea of someone who adheres to a routine, do not carry the same negative implications as "creature of habit".
