Ask HN: Will this hold me back when looking for investors?

Long story short, I have written a series of fitness books for a traditional publisher. They are a fun amusement for me at night. I'm pretty serious about fitness as a hobby and writing is a good outlet for that as well.

I also had a deal with my wife that when the kids got to a certain age, I could pursue my startup. They are approaching that age. I have been working on the prototype and should be ready to get in front of people in maybe a few months. I'm going to bootstrap as much as possible, though the nature of the venture requires I have a bit more capital than I can outlay myself.

Note: my venture has nothing to do with fitness so the overlap is zero.

My question is 1. would the books be seen as a negative by investors? I currently work in tech and get some pretty weird looks from people who know what I do on the side. I'm wondering if the same thing will happen when I sit down with potential investors. I'm sure it will come up in their due diligence. I'm wondering if I should address it directly or wait for it to come up. Obviously don't want to be written off as "a dumb jock".

Thanks in advance!
