Scaling up trade size after a good run - how do you manage the psychological aspect?

Hey everyone, been lurking for a while and learning a ton. So, I've had a pretty decent few months, managed to string together some winning trades, nothing massive but consistent enough that my account is up a fair bit. Now I'm at the point where my predetermined risk % per trade means I'm looking at significantly larger nominal amounts than I started with. And honestly, it's messing with my head a bit. The idea of risking, say, $500 on a single trade, even though it's still the same small percentage of my capital, feels a lot different than risking $50. I find myself hesitating more, sometimes even sizing down subconsciously. For those of you who've scaled up from smaller accounts, how did you get past that mental hurdle? Is it just about sticking to the plan and getting used to the numbers, or did you employ specific strategies to desensitize yourself to the larger figures?
