Can someone help me? :)

Can anybody help me get to gold?, Currently silver... ~Please don't interpret this as me asking to get boosted, I want help Improving, And actually deserving to be in gold.

I've been playing league for awhile now, and i just cant place what holding me back. I've tried tons of different things and none seems to work.

I truly believe i deserve to be in gold. Well , At least when i'm not busy tilting in my normal games aha.

There's like this invisible wall in front of me, there's a door leading to a better tomorrow but my eyes are unable to see this door...

It's like i'm missing something obvious
