Don't do it!! It will drive you mad!

Seriously, though I would suggest you start with some simple project like a bookcase. My original intent for woodworking was to make a MAME cab, but I haven't done it yet because:
(1) I've been making other stuff, partially as an excuse to buy the tools.
(2) I wanted to make my mistakes on the basic things and not the eventual cab.
(3) Lack of time, because a cab (at least for me) will probably take a lot of intense effort.
If you don't have experience woodworking, you have no idea all the little things that can go wrong. For example:
(1) Keeping the work clamped properly, especially while routing.
(2) Cleaning up all that wood glue before it dries which requires sanding to get rid of.
(3) Screwing up the measurements, or not being consistent with how you make cuts.
(4) Not thinking the design through properly.
(5) Half-assing things b/c it's friggin' hot outside!
(6) Not organizing your work area properly.
(7) Not knowing some trick or efficient way of making cuts, etc...
What is really aggravating is that I did a fair amount of reading first, and was aware of some of the pitfalls. Yet I did them anyway! (partially because of #5 above). Plus I am the type of guy that needs to fail to learn something.
So my advice is to start small. Build that bookcase your significant other wants. They will appreciate it!
