While I was talking with my co-workers, I couldn't help but notice that most of the things that I say or do to are to be more agreeable or funny.

My first idea to avoidprevent this from happening again is to acknowledge that I'm doing things to be more likable.

either of these would be typically expected:

1. My first idea to avoid this happening again...

or

2. My first idea to prevent this from happening again...

The second step is to think before I speak, I; it sounds trivial, but it avoids talking about things on auto-pilot.

I added the semicolon because "it sounds trivial" is an independent clause and either needs to start off in a new sentence, have a semicolon preceding it, or have a coordinating conjunction preceding it

Also, you could say "talking on auto-pilot" or "talking about _____ on auto-pilot"

That sounds very normal.

You had an extra word, but I think it was just a typo in this case.

Oh, I debated whether to make this comment.

I love the phrase "talk about" this way. It reminds me of a walk about -- a little mindless walk around the neighborhood. It's a creative use of language and it paints a good picture.

I think a lot of people might misunderstand it as a mistake, though. The English-speaking brain sees the phrase "talk about" and is waiting for a subject: "We talk about politics" or "Let's talk about literature" or something similar. Upon first read, I thought it was a mistake until I re-read it and thought of it like a walk about.
