I got interested in salt water fish tanks, I could not stop researching, posting on forums, reading anything that I could get to, to learn more about the subject. I would dream nightly of freaking
fish tanks, and wake up
in the middle of the night just to read more about the subject. I ended up spending about two grand on fish supplies, and then probably two months later, compeltely lost the interest in it.
The same has happened when I got my laptop, blackberry, ps3.
