I think that the grass is as green as you want it to be.
I personally have moved on from Engineering, and I found the grass to be very much greener. Not only financially but actually feeling satisfied with finishing tasks and completing projects, which I was not getting in engineering because I was being pushed from pillar to post all the time.
I think at the end of the day if you don't try you don't know, and the general concensous in DON'T even bother trying!!!
