How do I say this in Latin? Anyone?

Reputo, creo, provenio is fine. I would definitely not use cogito, seeing as it means I think in the sense I believe.

Thanks Kirara,

I really appreciate it. You are right, believe is not what I was going for here. Instead I meant 'to hold a thought'.

What about creo vs partum and provenio vs successio?

All the best,

Mark

Let's see...

Creo: I make, I create, I produce
Partum: I bring forth, I produce (Transf.: I create)

Provenio: I succeed
Successio: I succeed

As you can see, you can use any of the words above. I just didn't mention them, because I was focusing on what you shouldn't do: Use cogito. As for provenio and successio, there's little to no difference at all. Provenio can either mean to succeed or to turn out well, whereas the only sense of successio is to succeed. You can use either one in first person, singular to denote the same thing.

Thanks Kirara,

That's all I wanted to know!
