Determine if my own goals are private or personal

I can see the value in shared goal listing, it’s fun to read and navigate, but for me to get value out of this, I feel that I’d have to be really honest about myself and my goals – and I’m undecided as yet whether this is something I want to have on public display yet. There are various reasons – some involve embarrassment, others involve fear of others doing something before me, etc. I’ve still not found my own balance of public/private – maybe that’s why I’m such a lousy blogger (my most interesting entries are by far the most personal, and they are few and far between.)
