Come on, it is not about profiling or going out of your way to boast or seek attention. During your time in the classroom, by all means spend all the time focusing on delivering a good lesson and developing a good relationship with your students. But not all your time in school is spent in the classroom right? During those time when you are in the office, spend time getting to know your colleagues - you will be surprised how just smiling and spending a few seconds greeting others can make a difference. Listen and find out who needs help then volunteer to help instead of waiting for others to ask. Listen and ask others about their interests. If you think being a teacher is just going to school and spending time with your students only, you are wrong. There are many aspects of the job that would require you to need assistance and support from your colleagues. Offer help proactively and when you require support, it will be given to you willingly.
