Creating limits or setting parameters is essential to achieving peace of mind and protecting our well-being. Instead of using the term "set up boundaries," there are other phrases that can be used to convey the same message. For instance, establish limits, define parameters, or create guidelines. Other synonyms include install guardrails, erect barriers, fix perimeters, or demarcate areas. Defining space or outlining restrictions are also useful alternatives. In essence, these synonyms all share the same underlying principle: taking control of our lives and deciding what we will accept and what we will not.
