if you're hardstuck silver for thousands of games, don't give up, here's how i got out
My biggest problem was that i played way too much champions, in fact, i played 104 champs in ranked this sole season. Also, i had a huge problem of tilting. To get out of silver, you really need to find one winning strat, DON'T mess around EVER, or else, there is a really great odd that you will go on a losing streak or be stuck from playing too much random stuff. I finally decided to stick to one champion the most i could cause it was my best one, there isnt only winning strat, but here was mine :
i spammed 
and here is my winning build (of course there is other ways than diana surely xd)
(upgrade to 
if you get 10 stacks)
rush 
but if you have no engage on your team, you are better off building 
first (and then normal build)
get 
next get 
for stronger aas, it scales super well with nashor
and then ideally you want 
and/or 
but
if enemy got mr get 
or if your team is likely to throw or you may lose get 
to still be able to carry without dying
also this is not the only thing, here's the macro part (i'll speak for mid roaming champs cause its what i mostly play)
-Think all the time, dont ever do anything on impulse -Look the map, always look for opportunities -Never ever flame, even if your teammates think that you CAN carry them, youre the sole constant on your team -Don't lose time ever always do something -Avoid giving shutdown gold -Don't keep mindlessly grinding if you start losing, its just gonna get worse -Push your lane before roaming (maybe not that much if youre in a losing matchup you need to not fall behind, go take gold somewhere else, kill side laners or go in jg if you can to farm camps or kill the jungler(if you know where he is)) -never surrender always try your hardest, monkeys cant hold you back if you carry enough -use hp, mana, level and knowledge of your damage to know if you can kill -dont think about the flashy play, think about the most efficient one, helping to get objectives -never forget farming -ping all you can to control your braindead teammates
you can ask me more stuff if you want :)
