People are just as stupid if not more so - they simply rely on more complex solutions and are aware of yesterdays tactics - repeat next week. It seems OP is getting less and less creative or not motivated with enough sense of urgency to hustle.
I've learned to look at this game from a shitty little worm's point of view failing and getting trampled on 100% of my attempts, then became a soldier, 75% fails, some great spikey wins. Then became a general, launching an offer looking after many soldiers, 50% fails, then became a soldier again while being many generals of many products, then before I knew it - I was successful with a birds eye view of all the worm's, and other hawks to network with. Now it's more reactive and maintenance and about 80% wins, but they're daily and big and part of a powerful routine.
The fails were all important and I've learned from each one but I look at it like chess too - and if shit just kept getting worse and worse for me vs better and better, I'd change strategies or change games, try checkers for now. You're gonna keep failing until you change your game/routine, and even then you'll fail tons before finding something worth scaling for more than a quick spike (I've launched 40 or so offers, slaved over all of them, over half bombed, only 10 made money, only 5 made good money, only 1 has truly set me free and now grown into 10 more strategically placed protectors/branches of the big winner).
Fail as fast as you can.
