The internet. Breaking that down, without the internet, I would not have been able to make the money I have online to be able to buy every main series Pokemon game from Gen 3 to 7, physically, with now 1 and 2 being digital (once GS VC comes out). Then in 2015, having the most money I ever saved up, to buy everything to built a PC, which is still going strong 2 years later. I would not have been able to buy a Wii U, a PS4, 7 3DSes so far. I wouldn't be able to pay bills, or connect with certain people that have at one point or another made me genuinely happy. Material things sure, but after high school, with really nothing being done in my life, the internet has at least given me some form of direction, though I won't lie and say it has done this all the time. Without it, I certainly would not have even known half the movies I've watched and enjoyed such as The Room. I could go on about The Room and being grateful for that but I think my quoting and GIFs of it says enough.
I'll be even vaguer on more personal things to be grateful for. My mom, grandmother, and great grandmother, they take care of me, they have taken care of me, I'll never be able to repay them, and I'm very conscious of that. Also, in the distant past, my sisters. We're very much estranged now, but back then, they were just as much as friends to me as the ones I made out in the real world between childhood and my teenage years.
Also, to break it into 5 entities. I'm grateful for the following: Jackie Chan, Dragon Ball, Pokemon, Clint Eastwood, and porn. I could go more into them, especially porn because I don't mean what you see on the pro-side, and amateur is too vague as well, but again I won't do that.
