​i keep killing my own app ideas once i think about them properly is that a good sign?

ive been going through this cycle a lot lately

i get an idea, it sounds solid at first, then when i try to break it down properly it starts falling apart

usually around questions like

who actually needs this

would they switch from what they already use

is this even a real problem or just something that sounds cool

ive been trying to approach ideas more carefully now instead of jumping straight into features. even came across a book, i have an app idea while figuring this out and it made me realize how much i used to skip early on right now i dont have a specific idea locked in, more trying to improve how i evaluate them before building anything

is this a normal phase or does it mean im being too critical too early?
