Struggling to nail down a consistent risk % per trade, any tips?

Hey everyone, been lurking for a while and finally decided to post. I've been paper trading for a few months now and just started dipping my toes into live trading with a small account. My biggest hang-up right now is risk sizing. I've read all the standard advice about 1-2% per trade, but sometimes it feels really rigid, especially with different setups. Like, if I have a high-conviction setup with great confluence on a $NVDA or $TSLA play, I feel like I should size up a bit, but then I'm breaking my own rule. Other times, I have a more speculative idea, and even 1% feels like too much risk for the uncertainty involved.

Do any of you seasoned traders adjust your risk percentage based on the quality or confidence of the setup? Or do you stick religiously to a fixed percentage, no matter what? I'm trying to develop a system that's both disciplined and flexible enough to account for varying trade quality. How do you approach this without just gambling?
