The easiest cure for the "greener grass" syndrome is to try other DAWs. I found it very easy to harp on Sonar while every other DAW seemed mind-blowing. Then I switched to Studio One. After your first five-minutes waiting for a project to load, switching again doesn't sound like a bad idea. And that's just the first of the many problems I encountered. Yet, while I was a Sonar user, playing with S1 only casually, it seemed like heaven on earth. What I found most surprising, though, that switching from Sonar didn't really change the frequency of crashes I encountered, regardless of the DAW. That part literally shocked me.
I'm mostly on Cubase now (and liking it a fair amount), but Cubase has its own limitations. And, time and time again, I find myself missing Sonar. If this release delivers the goods, I haven't ruled out coming back.
The other advantage in trying other DAWs is the inspiration that can be gained from changes in the workflow. For example, StudioOne allows non-destructive rendering of clip effects. This resulted in me playing much more freely with processing short snippets of audio in all sorts of crazy ways without needing a gazillion tracks, and thus led me into a different direction than I might have taken otherwise.
