The best advice I was given, was also the first advice I was given. It is an airplane, just fly it like an airplane and don't worry about the FBW.
The number of times I "notice" that the airplane is not reacting quite like I wanted it to is extremely small. Maybe once or twice a year and only in moderate turbulence. And it is only because the FBW is faster than I am, and is already deflecting the control surfaces in the way they need to be deflected. I just got clued in a fraction of a second later.
