-take a break play when you feel relaxed
-don't get overconfident but don't be too passive
-remember even if you do get to silver 5 most likely you will be placed back in bronze next season unless you climb up a lot more i was gold/plat last season and got put in bronze 1 this season. However i did get some MMR decay for being inactive so it was a little more extreme but usually at the start of the next season unless your placements go really well or you climb up to gold or somehing before the season ends you most likely will get put back in bronze
So be happy you're improving but don't let this be the your end goal because the day after you hit silver you will probably realize your still play with the same range of players typically
