I lost motivation when I started spoofing as everything became too easy and low effort so I set myself limits and spoofed less (no gyms and not more often than playing legitimate). I found that more Effort input = value of what you achieve and spoofing reduces effort immensely. With everything so easily gained you will run out of motivation and focus on minor things like not being able to get a stone fast enough. Because everything else was so simply awarded via spoofing. Instant gratification & rushing to get everything will burn you out on the game. Spoofing should be complimentary to playing legit in my opinion (feel free to downvote). Go for a walk and a real hunt from time to time, that's what's rewarding about this genre. Otherwise we may as well play on the Gameboy, DS or 3ds.

You'll get a stone eventually, what's the rush?
