Have you ever gotten extremely lucky when mining? A block found with a CPU in the age of GPUs, two blocks in a day when you make BTC0.5/month, or something else that's statistically near-impossible?
Ummm... What?
Firstly, the "age of GPUs" has long since passed, and secondly if you're solo mining (even back in the "age of GPUs"), you might as well just play the lotto.
Sorry, but a few thousand kilohashes isn't going to find any blocks this side of forever.
