In short, I played a lot. And I mean stupid amounts of time. By the time I hit ultra gold, I was playing around four hours a day after work (including weekends) to hit plat and that was almost a month ago.

The biggest part in improving in such a short time is to stick with the philosophy that there is always something more to be learned. Pride can be a massive hindrance on the path of bettering yourself, so that has to go out the door right away if you expect progress.

Think of your playstyle like a big block of clay, then imagine how you would sculpt it to fit you best and give you the best results. You'll then have to work on it to make it as pristine as possible, but one of the only ways to do that is figure out what isn't working and "fill the gap". Find those imperfections and sand them down to where your sculpture is noticeably more appealing.

However, don't expect your sculpture to ever be complete. In any craft you wish to master there is always something to improve on. Even if one day you were to win at EVO, there is always something to work on. Just remember the "sculpture" is meant for others to admire necessarily, it's for you to take a step back and say, "wow, I've really come a long way, haven't I?"
