Well, first, congratulations on getting your first unsupervised dives in!
But some advice to make those dives more fun . . . See if you can find a good Marine Life ID class to take. I'll bet even the places where you were diving that seemed uninteresting had a lot of living things that were either too well camouflaged for you to spot them, or didn't seem interesting because you didn't know anything about them. My Marine ID class had the theme, "I want to show people there's more in Puget Sound than Wolf Eels and Octopus", and it worked; I see a lot more, and appreciate it more, for having taken the class.
That said, not all dives are going to be productive of tons of exciting things. But they're still diving!
