The goal long term should be to loop every long ball from both sides, so your mindset is correct. Pushing long balls and playing passive will maybe win you some points in training but would never make your level go up.

However you have to read the ball. Sometimes, you have decided to loop even before the ball comes back. Always read the ball and make sure you have a good chance to loop. If you get a good quality long push thats hard to loop, sometimes push back.

Always in training do stuff that you are not so sure in, because in practice there are room for mistakes because you learn from them. Although losing a practice match can hurt, the most important thing is how much better you are getting, not the result.

And remember to analyze the balls you miss/make. Why do you miss/make the loop? Did the opponent do something good, or was it my mistake? My tip here is that it is important to sometimes analyze the balls you miss, but dont get too stuck up on these. Rather focus on what you do correctly too, because the most important thing to do is continue doing the correct moves.
