I'm trying to find reasonable translations for the following:

 - I think, therefore I evolve
 - I think, therefore I progress

Ideally, I'm looking for something short starting with "cogito ergo" but I don't know if that applies in these cases, or if I'm trying to use the wrong English equivalents for what I'm trying to say.

Are there any other synonyms (such as "improve") that could be elegantly translated and make grammatical sense?
