Remember it doesn’t matter if you win or lose or what your winrate is.
You will never be pro anyway so your rank doesn’t matter. You do not get a higher prestige of life depending on your rank. You don’t need to feel embarrassed because you have a low rank. In fact, players that have lower ranks are more successful in life because it shows they have a life, rather than that person that is Diamond that failed all university assignments and plays 10 games a day just to show off with a digital rank that is worthless in the real world.
Just play to have fun. You do not need to care about your rank, if you win or lose or if you have a 13% winrate in Iron. On my other account I am 25% winrate Bronze 4 but I don’t care. I enjoy myself flaming others, running down lane, opening. It makes me happy.
