Ok, first tip. Dont even look at you're own teams scores, you don't decide how well they do, unless you refuse to flat out help them. They either do well or outmatched. All you can control is you're own play. Mute toxic teammates and drive on. Be selfish, play to get yourself fed, because its soloqueue and being mr good guy doesnt win games. Farm farm farm, ward ward ward, buy at least 1 pink a game, farm some more, if you dont have more farm than the enemy dont think about fighting them if you are both 100% hp. If they are super low and outfarm you it may warrant a consideration. Play any role, not just adc. learn at least one champ every role and fill. DONT CALL ROLE, just fill. Dont speak in chat unless its about the game, no whining or complaining, dont even give advice until after the game. This should be a good start, but im going to add one more super secret trick, just because at one point I was bronze 5 and carried myself all the way out.....Yess even carried as support some games..........FOCUS OBJECTIVES AND TOWERS, you cant make you're team, but you can guide them to objectives. Towers are the point of the game not kills, so NEVER EVER surrender. I almost just won a 3v5 where 2 of my teammates rage quit at each other pre min 10. The other two players followed my calls because i got fed, just so happens the game made it 45 mins and we hardly lost. Like nexus to nexus race. Enough about me though. Focus Objectives is the best tip I have.
