Something to consider:

It might not be what others are doing, but rather what they aren't.

When you're new, it's not all that unusual to be more conservative. It's also not unusual to get a little jaded if you've been doing it for a while. Then again, your students may have a bit more difficulty with the task, or your method may not be working for them.

One of the biggest challenges with being a CFI, and where I think you gain the most overall experience, is trying to address issues without a "one size fits all" approach. Different people are just that.

As others have said, don't get hung up on it. If your student has a concern, have them fly with someone else for a different perspective or talk to another instructor for some advice on things to do differently.
