This question was flagged as being similar to another question of mine, so I have to clarify that this question pertains to how I should introduce the concluding sentence, whereas the other one pertains to which position a bridge sentence should occupy in a paragraph of the body text. These are not at all the same questions, especially since I'm already assuming that the paragraph contains a proper concluding sentence in the other question.
I wonder how I should introduce a paragraph's concluding sentence without making it appear forced and detached from the supporting sentences. I have trouble with this since the supporting sentences often have already done enough to convince the reader of the topic sentence, so I have trouble writing concluding sentences that don't appear redundant, and it often feels abrupt if I insert a concluding sentence. Because of this, I have trouble beginning concluding sentences with anything other than "For these reasons", "Thus", or "Therefore" as well, and I also wonder if I should use such words to begin each conclusion.
This all pertains to the same problem: how do I begin writing a concluding sentence?
I have attempted to learn about this through simple sample paragraphs, but they've only taught me how to add a concluding sentence to simple paragraphs, if needed. Therefore, answers containing explanations that make use of difficult sample paragraphs would be of tremendous help.
