paragraphs don't flow and that it is generally a poor piece of writing in the end. One of my friends has even remarked that it feels like a face-to-face conversation, rather than a scientific essay or report. I wish it just flowed as I typed it!
Can you guys help steer me in right direction, because no doubt I will be writing a lot more in the future.
I think the answer is to take it one sentence at a time. You know what it is to write or speak a beautifully constructed sentence, don't you? Some sense the drumming rhythm, and they align with it, feeling meditative moments while the syllables massage the mind.
Here is a beautifully constructed sentence:
I certainly enjoyed what I learnt, but it was not 'perfect', so the question I asked myself after two years in the program was this: Can I apply physics in the workforce to something I would enjoy more, or alter the degree to incorporate something better.---- I added a colon and made a small change. This makes it even better. Can you enjoy the rhythm of this sentence?
Really, your writing is already great. Don't let anyone tell you otherwise! You do have awkwardness in these sentences that refer to questions, though:
Another question that I did not ask, but did research on, was a question of
how I could make a difference as a medical engineer on the community, or the world as a whole.--- this time, instead of using a colon I fixed it with "a question of" how could I ...
This sort of thing could be the reason your friend said you write like you speak. When you speak, you might say, "Another question that I did not ask, but did research on, was, "How I could make a difference as a medical engineer on the community, or the world as a whole."--- and even this is okay, if you write it in quotation marks.
