Buckle up. Im a top main so this is biased.
Find your favorite champ type like bruisers or adc or tanks. Then find the role or roles u like. Spam in norms with 1 to 3 champs that meet the previous rules. For example i do Swain, jax and maokai for Ad, Ap and tank for every team comp. Jax and mao can jungle where i flex amumu or elise to cover ap so if they go yas mid we get some ap for balanced comp. But at first just focus on 1 champ then a backup if banned. Thus allows you to focus on game 13356% more than a champ pool of 20 champs(why most people stay bronze). They focus on micro the whole time instead of macro and that is the result, go nowhere. So play a fun champ that you can play braindead so you learn matchups, power spikes, and objective priority. For example i can splitpush with jax with sheen and phage to 2 v 1 most ganks and get 2nd tower at 20 ish mins with triforce on a slower game. 15 if really fed. But i group after first tower only, because even if they stomp me, if they tp bot i get 3 waves and they just threw lead to allow me to take more towers, then i can group and be very relevant even if an item behind im not useless and i got a tower and gold for team, and pressure on map. Instead of just getting a useless kill and air drag then jerking off mid for 5 mins. When instead those 3 waves and tower give you 1000+ gold and 1.5 lvls. This took me so long to learn, but get a lead then group, dont just get nothing. Watch high elo streams, question EVERYTHING they do and why they did it, pause video when confused until u get why, then you will stomp low elo. Mechanics mean nothing, macro is everything
