Learning how to bet responsibly

Recently started getting into sports betting more seriously, but it feels like there’s a lot I’m missing in terms of structure and control. Sometimes I win a few bets and then end up losing everything because I keep going without a plan. Trying to understand how people actually stay consistent and don’t let short-term results affect their decisions. Is there a simple way to approach betting that reduces mistakes and helps build discipline over time without overcomplicating things?
