I understand your frustration - but - short of actually meeting with a personal trainer, the best we can offer is resources and personal opinions.
It really sounds like you're on target for increasing your running/cardio strength and speed - and I would agree, without knowing your specific running goal, it's difficult to suggest plans that have worked for others.
I spent a lot of time researching and learning what I was/am capable of with my own running, and as my abilities increase, my goals change. Try a few different things, and if you're still frustrated, I'd say you haven't really found the 'IT' thing that sparks your next interest with your running - keep looking, you'll find it.
I personally decided upon a race distance to focus on this year, set my sights on specific events, and worked the recommended training plans (each even had suggested training plans depending upon the goal and experience of the runner) - and it's really kept me on track with training. The biggest difficulty I ran into was trying to train for both a triathlon and a half marathon at the same time - believe me, those goals don't always mesh well!
