How do I get into High Elo?

I feel like I am a pretty decent player and most games I play I am the one doing the best on my Team, sometimes I do hit win streaks but they are met to an end by a losing streak. I am trying pretty much every lane but to no luck.

Just keep playing honestly, you wont be able to climb if you just keep taking breaks from ranked

Patience, consistency, practice, understanding game, mechanics of all champions, so basically just play as much as u can and try to understand why u died or why u lost everytime u make a mistake

Honestly? I'd recommend to get a paid coaching from someone who knows their shit. Took me two coachings to get from gold to diamond 5

Dude just play a lot and /muteall, not kidding if you do this you will climb, of course it will take some time, but you will be happy when you see that you climbed the ranks

if you want to get there then you need to practice and study a lot

Dude, you have to always try to be the best version of yourself as a player, and don't bother with "elo" it comes naturally once you start to always be better for yourself. Instead of worrying with being an elo-farmer, try to be the best laner/jungler of your street at least, it's already a good improvement and it will reflect in your elo naturally.

play 2 or 3 champions max, take breaks after 2 losses

keep playing and look at replays to see where you can improve, how you died, why, where was your vision lacking, etc

Find a game buddy that is not a shit. You can achieve high ranks easily
