goodlife - "Are You Benefiting Yourself?"
That's a very strange question. In linguistic terms, the question is practically meaningless. Let's see if the rest of your post makes more sense.
goodlife - "...Millions of people today want to know how to overcome problems and enjoy happy lives..."
Indeed they do. No question about that.
goodlife - "... History is a record of the events of man’s past..."
Can't argue with that. Next.
goodlife - "... There is more than one way of looking at such history, of course. On the one hand, it is said that those who refuse to learn from the past are condemned to repeat it..."
George Santayana said that. Specifically he said, "Those who cannot remember the past are condemned to repeat it.". However, you still haven't made a salient point or asked a question.
goodlife - "... On the other hand, many now assert that ‘history' is no benefit."
Do they? Who says that history is of no benefit? Names please. Also, is there a question in this? If there is, I cannot find it. Apart from the meaningless, "Are You Benefiting Yourself?" gibberish.
goodlife - Do us all - and yourself - a favour, and start writing your own questions rather than copy and pasting random quasi-philosophical claptrap.
