If you want to win, play with Confident

Don't go into game expecting your jungler to be a beast hyper carry who will gank, for all you know he could just afk farm the whole game expecting the same from you to carry while he doesn't have to gank

Don't go into game crying that you're going to lose because you're in a bad match up Or have no confident in a skill match up Or don't be a suckass when you're in a good match-up otherwise you can only blame yourself when you lost that good match up yourself

Make play you know you can make, and not think if you can or not...... If you know you can "JUST DO IT"

Don't try to be a smartass and in denial about mistake that are caught by you from your team. You know you fuck up but you refuse to believe it and that what also cost you the game as well. Don't expect your team to follow up correctly when you want to engage a fight. (When you engage just focus on who you want to kill and get that target even if it mean you'll die as well but it will at least make it worth

If you keep telling yourself elo Ranked matter then you deserve to not climb because elo Ranked don't matter. I'm Gold and I beat most Plat and Boosted Plat that I lane against. (If you can't play better than a Plat or go even, it obviously mean you're not ready to be a Plat because you're not at that level)
