New seller stuck sourcing for days and can’t seem find a SINGLE profitable ASIN

Pretty newer seller and I’m honestly stuck.

I’m only a few sales away from hitting 204 Account Health, but I’ve spent hours and hours every day and can’t seem to find anything worth while asins

I’m reverse sourcing storefronts, using Keepa/SellerAmp, checking fees, ROI, competition and everything either

• Has tanked Keepa charts • Too many FBA sellers / race to the bottom • ROI under 15–20% after fees • Gated / brand issues • Or price is already collapsing 

For those of you who have been through this stage:

• What do you change when sourcing just goes completely dry like this? • Are there specific categories, store types, or methods you switch to when OA stops working? • Is this a normal phase before things “click” or am I missing something fundamental? 

I’m not looking for leads just trying to understand what experienced sellers do when they hit a wall like this? Just keep trying????

Any advice ?
