As for me,

As for me,
 

As for me, I can tell you that.....
Abot me, I can tell you
the second one sounds odd to me. Is that correct?

As for me, I can tell you that....I prefer coffee over tea.
or
Personally, I prefer coffee over tea.
or
What I can tell you about myself is that I prefer coffee over tea.
or similarly
What I can tell you about myself is this, I prefer coffee over tea.

That question is ambiguous. It is correct that it should sound odd, because it makes no sense. Please give the Spanish, because it depends on what you want to say.

Edit: cross-posting. I thought he could also mean 'my opinion', in 'as far as I'm concerned'

As for me = En cuanto a mí,...

About me = Acerca de mí, ...


Can you see the difference?
