Can you please correct these sentences. Thanks. №39

Taking into account the rashness of most of his actions, he seems to be a very lucky man. Just remember his half-month trip to South Africa. He was totally unprepared for it and ran into trouble with strange local laws.
As I anticipated, he has flatly denied this. But what I really didn’t expect is he is ready to ask some of his friends with experience in business to answer to my questions.
Upon my word (quite old fashioned!), I wouldn’t leave the house if I wasn’t fully confident that everything would be ok and there would be no danger for her. At the end she looked quite well when I went home.
You can not refuse this reward. I am sure that you completely merited it. If you don’t think so a better way to dispose of this money is to transfer it to a charity.
I have to apologize. During our last talk I said many things about your way of life, which I sincerely believe to be true. By no means I had intended to offend you, but I strongly advise you to begin a new life, work harder, do some sports and sleep a little bit more.
He is a very well-educated person, but when it comes to discussions he stubbornly adheres to his point of view and concedes no other opinions.
She considered it an indignity, but didn’t show her resentment. Overall everything goes according to her plan and it was enough to her complacency (? can you give a synonym?  Meaning unclear).
If the flight hadn’t been delayed I would probably have arrived for the concert in time. It was the last concert given by this band and according to their statements in the press, they will never give another concert as a single band. However it is possible that some of them will continue their professional careers individually.
She said this with such unconcealed cunning that everybody began to suspect that something is wrong with this event.
