It's very reasonable to take a step back and reassess at the first indication of unexpected resistance. When you decide to do something, you're making that decision based on how you expect things to go; if they aren't going that way then the assumptions underpinning your decision to go down this path no longer hold. If you wouldn't have started had you'd known there would be even slight inconvenience, it means you don't value the output enough to justify that slight inconvenience, and you should not keep going just because of sunk cost.

Being lazy, ie being particularly unwilling to put in much effort for a reward, is quite orthogonal to how long you keep pursuing a particular approach to achieve a reward.
