Ask HN: What do you do when too many people want to “help” your startup?

Some background: I am bootstrapping a startup by working part-time at a few jobs. This isn't going as quickly as I would like, but it is what it is. (I have obligations that I'm unable to blow-off to launch it full-time.) I haven't even told that many people about it - just those that ask what I'm doing in my "free" time - and am not advertising it.

The problem is that everyone is offering their help (literally every. single. person. who finds out about it). I don't talk about it anymore, and won't until it's ready. I would actually like to keep my personal life separate from my business life as much as I can. In three different instances, I have witnessed businesses (and money) destroy lives in my own family, so this hits home. Also, and I'm not sure how to put this tactfully, even though I think the people offering to help feel like they would be doing me a favor (and this is definitely true in some regard), I am not a fan of their work ethic, among other things. They may have an inkling as to how obsessive I am, but working together would be a problem.

Has anyone else had this conflict? And if so, what did you decide and what happened? Am I being short-sighted by ignoring help?

Thanks!
