I agree 100% - it's sometimes hard to imagine that we actually have something to offer a successful or powerful person. The only thing I would be wary about is that you may write "let me tell you something fascinating about XYZ which I have discovered." A busy person may read that as "let me take up even more of your time boring you to tears with some bullshit about XYZ that I made up so you'd take my meeting." If you don't truly have something interesting to share then you shouldn't write that just to get a meeting. The OP posted that specific text, but I think what he was really getting at was just being considerate and original.
