There is an idea that this addiction (yes, I do classify it as an addiction) is something to be fought, that you need to be David to fight against the mighty Goliath, that this will be the hardest habit ever to break. Once again this is wrong.
While humbling yourself is important, and definitely better than the alternative of overconfidence, the simple logic is that it all boils down to a choice. You’ve just been choosing wrong this whole time, and it’s developed into something pathological (hence the term addiction). There isn’t anything to fight. You don’t have to attain some arbitrary herculean willpower to obtain the necessary ‘pre-requisites’ in order to finally say, “oh, I’m so strong now, I can finally stop taking the slide”. You’re just setting a cage for yourself, an unnecessary limit you have to reach first. All you have to do is just WALK AWAY and not take the slide.
Here’s a post where @Luffychwan explains his similar thoughts, although in a much harsher manner than I do

Yes, you can literally CHOOSE to stop right now. You don’t have to reach a 100+ streak, or wake up at 6am every day for a marathon. Just stop now. The rest will come later.
