Those things usually pair with each other so i just jumped on the thought train i guess. My bad. Ignore the 5th point then. 3rd one is still most important. I'm gonna expand it a little. I can think of 2 ways to self-improve gameplay:
#1 - The key is to analyze your gameplay with questions (easiest way imo) - Why did you fail lane? Why did you lose? What could you do to prevent it? Questions are endless but it will give you idea where is the issue is and what to do about it. You will succeed next time, as you already experienced it.
#2 - In some cases you do everything you know pretty well and still can't climb - that's because you don't know everything. It's time for you to look at people better than you - what do they do you don't? It's mostly useful when you climb the mid elo but that doesn't stop you in any case. It really helped me back in season 3 where i first time played ranked seriously.

i was actually speaking to some friends who are all D+ and they say if you can get out of plat which is really elo hell...then you can make it to higher elo diamond...
Tell this to ~60% of people who are stuck in V division of diamond (stats)
