How long does the buzz last.

Hi guys right now i'm in a buzz over restarting my tank. I'm on the net gathering info, what i'm going to buy , what to buy first anyway you get the picture. I'd say 80% of the fun in the hobby is setting up a tank.

Now how long does it last; what's the thing that you think will annoy you or did annoy you the first when the routine gets in .
