Meaning of 'as far as I'm concerned'

[Jesus1]

Hello! How are you?

Could somebody explain to me the meaning of "As far As I am concerned..." using some examples?

Thanks a lot!
Jes?s.

Hi Jes?s

As far as I'm concerned means in my opinion.

As far as I'm concerned, it should be easy for you to use this expression now.

Thanks a million, Amy!

Easy, really!

I think it really means "in as much as it effects me" or "in as much as it matters to me".

As far as I'm concerned it doesn't matter what you do because it doesn't effect me.
or

As far as I am concerned I want you to understand the expression properly, because I want you to speak perfect English.
