Μετάφραση - Ιταλικά-Αγγλικά - non potrò fare ciò come mi pare.

It will pass in English, however the first line is awkward just the same. What makes it so is the word "that" in the sentence "I won't to be able to do that as I like to do it".
Possible alternatives which are less awkward in English:
I won't be able to do as I like to.
I won't be able to do as I would have liked to.
I won't be able to do that as I would have liked to do it.
I won't be able to do that as I would like to.

And so on. But it is good enough as it stands to be put to a vote.

Thanks, David!

It was just tough to me to translate that "come mi pare" from Italian. That's too "Latin" to be expressed properly in English.
