Clubs, Associations, Extracurriculars; how many is too many?

It's going to be tough to balance, but I plan on being in 3 clubs (2 academic, 1 social), a couple of IM Sports, and community work- most likely habitat for humanity. I want to meet as many people as possible and network. Class will be a lot of work, but i'm not to worried about it. From what alumni and current students say; b-school is more about networking than anything.

I've been told over and over again by students and alumni that the following process takes place inevitably year after year:

1) Student gets "involved" (writes down his e-mail on the communications list) in a lot of clubs. Probably about 10 - 15, with as much as 3 or 4 sports ones, 3 or 4 social ones, and then a good number of professional ones.

2) Student does not have time to be actively involved in all those clubs, so at some clubs he/she just stays informed of what's going on through the e-mail lists and at others he/she becomes more involved.

3) Student narrows down his/her career targets and remains actively involved in 1 or 2 (at the most) professional clubs.

4) Student figures out that the rugby/soccer/sailing and rowing clubs have conflicting schedules and chooses the one which he or she likes the most and drops the rest.

5) Student figures out that he or she does not have time to be involved in the Latino, Latin - American, Texas and Asian Clubs and focuses on the one which throws the best parties or which provides the best food.

6) Student finally narrows down the number of clubs to a manageable amount of -about- 4 to 5.

I don't expect to be above this pattern. I will subscribe to a lot of clubs and narrow it down later. I'll rather "test-drive" the clubs than be involved in too few of them and be stuck with them. I voted 4 as my final "steady state" number of clubs, but I will start with more than those.
