I went so long in the past without money, its so scary to actually spend money.
No.
My personal Sunset Rule might be handy.
If I can't make a sale by sunset, I figure my idea is worthless + I get a new idea.
You can scale this also... so if I can't make several $1000s of sales for a few hours work, then I get a new idea also.
Tip: If you make sales for $0 investment, you can never go upside down + your idea will scale forever.
