I'm not saying you should be careless, but I am saying that the way you put in effort is by having good, healthy relationships with others around you. I think the kid needs guidance and mentorship on how to become a self-confident person more than anything.
Completely agreed that it is harder to find people to meet. But also, the people you meet in your late 20s/early 30s will be much more mature than those you meet earlier in life, so it's not all bad.
Gender skew is a very serious problem -- but the student is primarily in need of guidance about self-confidence. And again, some comments have pointed out that there are more women at Berkeley than men.
