Agreed. Even if all you learn is the difference between validity and truth, this is an especially worthwhile difference to hammer into your brain. A lot of poor thinking comes not from invalid reasoning, but from hidden assumptions that are untrue. Conversely, the identification of contradiction is a skill that can be practiced with formal logic, and most invalid and convoluted arguments are easiest to unravel by finding those contradictions.
