It is my pleasure to teach each and every one of you. As we all know, we only have 24 hours a day. Each session that I allocate for you is precious to me as well. I give my full commitment in passing the right knowledge.
Thus, it is only fair that I give my time to students who will also return full commitment towards learning and picking up knowledge from me. It takes two to tango!
If you show a sluggish attitude, it is not possible for me to continue my enthusiasm. This, I believe you would agree.
Just share some correspondence (attached) with you. Treasure the opportunity given to you, don’t lose it.
