1. Present simple tense: Used throughout the answer (e.g., "setting clear boundaries is key," "I always try," "I set up") to describe habits and routines, which is appropriate for this type of question.
2. Infinitive of purpose: "to balancing work and life" and "to stick to fixed work hours" show the use of infinitives to explain reasons or purposes.
3. Conditional clause: "If I'm working from home, I set up a dedicated workspace..." uses a first conditional structure to talk about a real situation and its result.
4. Causative structure: "This really helps me maintain a healthy separation..." uses the verb "help" followed by the bare infinitive (maintain), which is a natural and correct structure in spoken English.
