    Yes. But the second "it" is redundant (and ungrammatical); thus ". . . a problem that at some point you found impossible." – curious-proofreader Sep 13 '16 at 7:27

It's ok but seems lengthy. You could convey the same point in a shorter sentence

“It feels so good to solve a problem that at one point seemed impossible."
