It's anything but dull to me, with the right setup it is incredibly immersive, beautiful scenery and some challenging approaches to ports like Shriver in the Ovid system, money is just a bonus.
I guess given your day job I can see the attraction there.
I've said to a mate a few times when he's been off pew pewing in a haz res and I've been sneaking around Robi smuggling, or he's been off exploring and hasn't seen another ship for a week whilst I'm slaughtering fools in a combat zone for a CG; best thing about the game is that we're in the mood for doing totally different things that provide a completely different game experience, yet we're both playing the same game.
I get bored doing A > B trading after about 15 minutes but doing it the way you're doing it can be good fun. When I'm in the mood for playing some missons I will often accept one at wherever I am and take off with a rule that I have to accept a mission at the drop off point, then I just carry on doing that for a couple of hours and find that I'm 250 LY away from where I started and have gone from delivering emergency medical aid to smuggling landmines. Then I sit quietly for a minute and examine my conscience
