I feel like a pretty lame summarizer. I am a plain to the point type of person that probably writes in that manner, I don't like to write if there is not a direct compensation in some way personally, and I think I sometimes miss the point totally and can interpret things really wrong at times.
If I were to get paid to do this I would need to really figure out how to increase my skills greatly. I read quite a bit therefore I know what good writing is and therefore I don't think that I am a creative enough writer to make it really interesting, even while summarizing. I can give a basic overview if that is interesting enough, just giving the main points. Sounds easy enough yet I know that I am not a writer, I don't have things floating in my head that are clever and that need to be written down. I must wonder though, how did Virginia Wolf get so clever at writing?
I do understand that effective communication is necessary in life, business and even in Girl Scout meetings with eight preteens in attendance. To put it bluntly, the business of writing is critically important especially in many professional fields. Therefore, if it helps my sales in a business, or my career as a nurse, or a researcher, then I will painstakingly do my best. One thing that comes a bit easier to me is creating simple ads and flyers. Sometimes I can write out things to help out my friends, editing, or even help overcome a software issue. Helping a friend is compensation, doing something nice for someone else. It doesn't mean that I am good at it, just because someone wanted my advice or needed my help. I am sure most people in the world better at writing than me; many of them still in grade school!
It is sometimes like a bad joke that my Cuban/German American friend tells me. It takes me a week to get the punch line if I ever get it at all, not sure if it is his accent or the meaning of the joke. Or like the time I tried to help my daughter in interpret a poem in high school. I told her exactly what I thought about the poem after studying it for half an hour. I thought it was totally obscene, morbid and immodest. Turned out she googled the poem got some others advice, and interpreted it herself quite well. She rejected everything I had to say and got a good grade. It turned out that I was totally off base and nowhere near the enigmatic meaning of the dark poem. My impression was very far wrong and I went further by making it political. I realize I do this, like when I sing the wrong words to songs on the radio. It's the way I hear it though. I misunderstand things all the time, that is why summarizing can be difficult for me.
So anyway, when I have to summarize something, especially something that will hopefully get me and "A" in a class, it really helps me to understand what I read better even though I hate doing it. I don't write creatively, especially if there is not much in it for me, I am blunt, and hopefully I don't get the content all wrong when I am summarizing. However, if I summarize by writing, I usually get the content less wrong, I helps me read better. Let me summarize, I hate to write but I do what I have to; it makes me better.
