All the money went in before the flop, and it was a 70/30 flip, which per definition you will lose 3 out of 10 times. Sure its a wacky runout, where you both make a full house, and his is better. But why does it matter, if you lose on AT822, AKQA7, QJ773 or 9862T? Its just, that you felt excited, when you flopped a set, but as the outcome show, its not over, till all cards are dealt. So in many ways its better to not even look but focus on other tables instead, where you have decisions to make.
If you want to improve, you need to focus on
hands, where you had difficult decisions to make. In this hand you made the only play, that makes any sort of sense. And then the rest simply does not matter. Leaning to focus only on things, that matter, is the key to becoming a successfull poker player
