Yeah, I'm the epitome of lazy. I've been cubing since April 2015, so about 8 months. My pb Ave is 12.56 and my pb is 8.something something. I still haven't learned one look OLL, and really I feel like it's too late for me now. Because of this, my LL takes me 4-5 seconds (yuck). Help
No; nowhere near too late. I can't think of a speed at which it's too late to learn full OLL, and to be honest I'm not even clear why you thought there was. Even if you averaged 8 seconds already, my advice would be "learn 1-look OLL; you'll be slower at first but you'll probably be sub 7.5 once you get used to it." For sure, do it.
Lots of the algs are repetitive and easy to memorize. For example, F R U R' U' F' is an alg that I'm sure you know, and many of the OLLs are based on that. Learn all the cases that are F sexy F', F double sexy F', and the inverses of both of those. Also, there are plenty of algs that are Sune variants. You know the alg R U R' U R U2 R'. Learn r U R' U R U2 r', as it's nearly the same. Also learn the algs that are sune with a sexy move inserted in the middle, as well as the inverse of those.
OLLs 5, 6, 7, 8, 43, 44, 45, 46, 47, 48, 51, 53, and 54 all fall under the category of algs that you pretty much already know. Start with those.
