Seems to me octopulse is on the right track. I generally find getting involved in some project is likely to keep me honest and productive. Perhaps you want to come up with your own project though.
Another thought I had was contacting a professor at a university and prehaps trying to set up a new curriculum. Perhaps some kind of 2 year degree or some sort of certificate program to offer more general ocean studies degrees.
Me, I'd try to work with a program like octopulse suggests. I too like a little pressure to force me to be productive, but you don't want it to ruin your fun either.
