Actually this is an interesting question since I am having the same struggles now. I'm trying to do something more and bring the regression to the next level.
For now I just started to take note of every failing test case to see why they do it/ how stable they are/ why they aren't (if that's the case). I also try to keep up to date with everything that is new here so I am better prepared for the possible situations I might encounter at work.
Another thing I want to change in my SoapUI tests is to make my tests more clear and more simple. Ideally everything in my project should be understandable by a novice.
