Neither do I, but there should be a comma before the "but" there.

No: these are dependent clauses, a comma would be incorrect.

What you just wrote is a comma splice, by the way. You should read up on semicolons.

Actually a comma is needed because that is a compound sentence. The 2nd independent clause has a subject of "you" (implied) and a verb of "learn."
