Bootstrapping a business is normal outside of tech, and common in tech when outside of SV. Not only is it a good thing, it allows you to be more sustainable. VC will push you to be huge - to them, a small successful business is a failure: They need monster-sized successes. So they will push you to take large risks to get you there, and not really care if those risks cause your business to fail because they are pushing a dozen other people like you to do the same.

So if you are happy with the money and passionate about the space, you'd honestly be nuts to take VC funding.
