one tip I should not give, but I cant resist its so good, but World of Darkness its possibly the best and easiest start you can get into RPGs. I would give it 10 out of 10.
This isn't a tip so much as it's an opinion, though part of it is also technically wrong. WoD is trumped in ease-of-use by about a dozen systems (objectively speaking one could mention RISUS, BFRPG, Amber, and others) and then a variable number based on user (subjectively speaking I would mention FFRPG, Iron Kingdoms, and any of the WH40K systems). Now, this isn't to say your opinion is wrong when it comes to it being the best, because opinions are opinions, just that it's not objectively the easiest start you can get.

Don't just buy an RPG a read it from cover to cover, its the wrong thing to do... once you can play an RPG then read the full RPG book.
This is also technically an opinion, but if we're talking "time-savers" then it's sort of a gray area. Sometimes you don't know what you're looking for, or the book is written in such a way that it's more like reading a novel than it is reading a dictionary or phone book. It's also not wrong to do if you like reading systems that way, but it
does save time, and it's not for everyone, so... I can't really disagree, in the end.
Otherwise, for tips of my own, you might also check out resources on this site when it comes to learning systems. There are things like pre-made character sheets formatted for this site to long discussions about different mechanics within specific systems. Talking to other people is often faster and more-comprehensive than learning by just reading.
You should still read the books, but talking to people for clarifications is a beautiful thing.
When there are no Youtube videos available (which happens) - and even if there ARE videos, honestly - I recommend taking a look at the examples characters in the book somewhere (which there almost always are). As Isida said, see what the system expects from you rather than trying to figure out "what your numbers should look like" on your own. People play games different ways, and every individual game run on this (or any) site is going to have something unique about its expectations, but knowing what the core game expects from you is just as important.
Never be afraid to ask for something new. If you want a Mecha-style game, but you only know Pathfinder, ask people about other systems. Maybe you'll find something you love, and it's a lot easier than trying to convert a system into something it's not.
