When to use 'I myself'

[edmondng]

When do we use the phrase 'I myself' in a sentence? Is the word 'myself' used only for purpose of emphasis?

I am writing an article and wish to use the following sentence:

I myself have lived a relatively good life before
​

Is the sentence grammatically correct? Is it better not to use 'myself'?

The sentence is grammatically correct. Myself - used for emphasis, my own self or person; as I myself will do it; I have done it myself; -- used also instead of me, as the object of the first person of a reflexive verb, without emphasis; as, I will defend myself.
It is perfectly ok as long as it refer to subject of the sentence. When it does not refer to the subject of the sentence as: He was an enthusiastic fisherman like myself. such usage is not appropriate though some people like to contruct sentences this way.

Yes, it is certainly better not to use "myself" in this way. There is never a need to use "I myself".
