It's unfair that you lose just because you placed a log once T.T

How is that unfair? If you dropped a log, losing is only natural. At least you had a chance, right? The fact that you couldn't capitalize on that chance is on you, and that's how you find a way to improve. Losing is normal, and if you start blaming others for it, you'll never get better.

What's truly unfair and disgusting is being put in a situation where you can't even pick up the log at all. In those cases, blaming others is totally justified.
