I get that and I don't expect anything else but I don't really care, as I'm just a 1-man-army with 0 funds.

50 people - heck even 10 - who think my product is worth using and I'm happy. That's how low my expectations are, just to keep myself sane :)

(I'm obv. not counting on this product making me a full-time income. I'm doing it for the experience and to get a feel for the industry.)

Imagine how many founder thought like you - "I'm obv. not counting on this product making me a full-time income" Because right now "context" your thinking is different. As soon as people taste the blood(success), it ain't this thinking anywhere. We are emotional being at core. Jealousy, greed, ambition affects everyone including Himalayan Monk.

Yeah, I'd love it if 10-50 paying users a month paid [part of] my bills. :D

We'll see though, and you are right that keeping low expectations is a key.

Plus a lot of the time you're not competing against other companies with similar products so much as all of you collectively are competing against customers' in-house excel abominations.
