Here's a helpful list that may clear up what makes a style complete for its practitioner:
1) If your training goal is to feel pleasant on a semi permanent basis, using your pleasantness as a weapon against those who don't conform to universal bliss, then the path you should take would require pot, pajamas, lots of soft touching, and Enya in order to be seen as complete. This path would also require weapons be used in a non-dangerous manner.
2) If your training goal is to come dangerously close to training in a way that might involve you getting hit by somebody, you have two options:
a) Join a school that does more push ups than other schools. Combined with their weekly forms, your feeling of smug superiority will be unbeatable!
b) Join a school that uses rash guards. Remember, if a school uses rash guards, it's owner is by default good! But don't think that rash guards are all you need. What pot, belly dancer pants, and 60's pop culture are to the tai chi hippy, a shaven head, the right brand pads, and a rash guard are to you. And don't be caught citing last years winner, because even your "Pain" tatoo won't impress anyone if you're screaming "armbar" in the year of the stomp.
Either of these options could be deemed complete.
Finally,
3) If your goal is to learn how to honestly use this stuff,
-find the best people that teach each of the skill sets you need to know, and don't settle on learning "everything this guy has" when you just want to know his specialty.
-prioritize what you specialize in based on your skill and build
-practice it realistically
-Stay off the forums and don't do drugs.
