Highest income month

I have been gradually increasing my income month by month. My goal for September is$14,000 which will be my biggest month ever. I have earned $13,000 in a month before, but that was nearly 3 years ago. It felt like a fluke that I couldn’t repeat.
Now though, my income more reliable. $14,000 is possible. It’s just that my head gets scared because it feels like a big number, and I will be stepping into new mental territory.

My goal is not only to earn $14,000 in September, but make it repeatable (the opposite of a fluke) and also to feel happy and sure it will happen. Rather than scared.
