Positive interactive experience for casual online players

I need help because I want this game to feel like a simple and positive interactive experience, but in reality I often find myself overthinking and losing that casual mindset. Instead of enjoying the process, I sometimes get stressed about my decisions and worry about making mistakes, which affects my overall experience. I would like to learn how to treat the game more lightly, understand its basic mechanics better, and avoid unnecessary pressure so that I can enjoy it as a relaxed form of entertainment rather than something mentally exhausting.
