Haha, it's okay bro.
Youll learn from these threads and not make another one.

Dont "wut kewb shud i gt?" thread, or people will frown. D:
The trick is practice, since even LBL with a 4LLL can lead to sub 20.
Learn all PLLs, and chill on OLLs, since recognition and having the OLLs with the oriented cross can still be quite fast. The time you save on recognition and knowledge of the algs might give you an advantage over someone who knows 56 olls, but arent fully associated with them
I know this from experience, since during my 17.01 avg at horizons, I forgot an OLL that i had learned 2 months prior.
Also, F2l should be the main focus. A good cube will help, find a good cube after some experimentation and stick with that cube. This lets you cut corners and be more accurate.
Trying Bright or Florescent stickers to contrast with darker stickers can help recognition. I.e. Florescent green across from blue, and Florescent orange across from red.
In the end, the most important thing is practice, if you read nothing else.
EDIT:
Um...get a type C. That will improve your times a lot.
Do this for sure, I love my green type C, even after a year, its still good.
