It starts out like it always does. You get to a nice rythym, upgrading and attacking. It's going well.
Then you get that one attack where they steal practically all your shit.
You try to attack back, but you're forces are small, and their base is better than yours.
So in response to this, you try to upgrade your village but you don't have enough shit. You're running on fumes.
Then you get attacked multiple times, and your resources are down to basically nothing.
Due to a poor lack of resources, you cannot attack, or upgrade to get better defenses, and you get stuck in this hopeless rut.
And you may be thinking: Why didn't you spend some money to get more resources?
The answer? I'm not spending money on fucking Clash of Clans.
