Dera friends.
I think that "what I say and what I do"... is grammatically correct and follow the rule of the same verb form joined by and.
Please tell me what am I thinking wrong. Thanks a lot.

Yes, that's right and that's the answer!

Hello,
Why what I said and.....is incorrect?

Thanks,

[Alan]

Hi,

It seems to make sense that 'say' and 'do' are natural partners and that changing the balance to 'said' and 'do' would sound odd. After all this is a comment made by someone who is making a general statement applying to all time and in that respect present simple (say) is the most suitable choice.
