Chess: want to get better fast

[Popinjay]

I want to get better at chess, fast. I mostly play 30min-1.5hr games (1hr - 3hr total) and want to get better at chess. I know there are some very highly rated players here, so I was wonder if I could get some specific advice as to how I should proceed in getting better. Give me a plan or something, with details!

About me, I am rated like 1150? in real life chess. I play the Giuco Piano as white and know it sort of. I say I play Evans Gambit with it but I hardly know anything about it besides the fact that it is b4. As black I play the sicilian dragon and know a little bit about it. I am decent at longer games (30min+) but really suck hard at speed. My fast tactical game is really lacking. Please help me.
