At least for me, the decision to not seek funding sort of answered itself. I didn't know who or how to ask for money, but I did know to program the tool I envisioned. Fast forward 3 years and I've got a moderately profitable business, and no investors. The work is fun, and no one tells me what to do.
I'm just always curious about others who seek the go the investor route. Do most of them actually get funding? If so, when? How? In most cases, I see people talk a lot about investors, but I very rarely see anyone actually get investment money. I'm skeptical that it even exists for the typical first-time entrepreneur.
You seem to have found your destiny. Why do you even care what other people think/do? I would say: follow your path perseveringly and you will end up fine. Not having the urgent need to think about the "investor route" is a good thing. Everybody additionally involved is going to meddle one way or another.
