new product didn't make money in the first month or two? abandon it and make a new product
new product DID make money in the first few months, but not now? abandon it and make a new product
new product made A LOT of money? well, that success isn't real somehow, better throw all that progress away and try something totally disconnected and more ~ambitious~
(you laugh but i've seen this so many times)
I shipped it, now I'm done.
I'm bored, I quit.
Product isn't making sales, but instead of working to make sales, continuously working on the product.
if the product doesn't sell itself, it's not good enough, I'm not good enough, I quit
get distracted by shiny new whatever, feel guilty about neglecting the product, but instead of doing a little emotional labor to go back to it, quit forever in shame.
someone else is doing something similar, I quit
regurgitating deep-sounding business crap like "market saturation" without ever even looking up what that means, as an excuse to not try
"Nobody would buy from ME" without ever attempting it to find out
"I'm not good enough, and no, I will not look around to see if there are people not as good as me who are doing better than me"
doing the same things over & over when they don't work
