How to write that very first sentence in an essay

Hello everyone, hope you are doing well, All the time I come with a new video, I try to focus on writing , at the end it is the most difficult skill when it comes to language , some would say speaking , but academic writing is a nightmare add to that the fact we need to write for exams, well you know the result.
Well today’s video is about the same matter but the focus today is on the level sentence . We literally are going to write one sentence, not any sentence, that very first sentence in an essay.
Often when you read about this , we find that a first sentence has to grasp the readers’ intention, to be creative , and a lot of similar stuff ……….. sadly while there seems an agreement of how this sentence should be , there is a little on how you can practically start writing it. I always find it so daunting to start , I write, scratch, write scratch , waste a lot of time , I remember when I used to be a student , that very first sentence was mainly the responsible for the time I spent in the exam. Let us face it, all the elements are often memorized or ready definitions , but that first sentence is like a glue that binds all element together and it is highly related to the way the question is verbalized.
