There are tons of people who have bios like this, especially in San Francisco. You quickly come to realize that most of the people who have done 50 million different "impressive" things in a short period of time are either dilettantes who seek the most recognition for the least work investment, or people who have one or two serious interests, and a strong ability to promote all of their other minor achievements.

(Protip: my vanity meter goes off the scale when the self-promoter is a woman who prominently features her amateur modeling portfolio on a personal website, or intermixes pictures of herself in a bikini in otherwise unrelated content.)

I think the thing to learn here is that noise level for self-promotion is set pretty high. If you think you're bragging too much about an accomplishment...well, you probably aren't. ;-)
