Confusion using simple past and past perfect tenses.

[aachu]

Though it may invite ridicule but I have to say. I don't know when to use simple past and perfect tenses. Can anyone of the kind teachers please tell what does it take to make past simple a past perfect tense? I mean how old an event can be categorized into a past perfect tense?

For example I say, "I made so many mistake in my article".
When am I supposed to say , "I had made so many mistakes in my article"?

thanks in anticipation.

Apart from in counterfactual conditional utterances, you do not need to use the past perfect unless you wish to make it absolutely clear that one past action occurred before a later past action, as in:

When I arrived, he had left.

Sir Fivejj thank you for your valuable post. Now, what I could get from your above post and the links you advised me to have a look at, I should try not to use past perfect tense in sentences like: I had made so many mistakes. Is that so? Simple past would suffice in these kind of sentences. Rest, i.e. use in counter-factual scenarios, and describing an event that has occurred before another, is very much understood.

It's impossible to say without more context.
