Just build whatever it says, then every game take a moment to read what you're building and eventually you'll start to realize why you build certain things
And you get back into it by playing the game (of all things, this may be surprising)
I don't necessarily agree that you should follow guides, especially this website's. For example, look at how they skill Axe, you don't max counter helix until far later in the game, which implies they are not jungling Axe; I highly doubt that you will ever see Axe in lane, since his laning phase is pretty abysmal unless you go mana boots + hunger spam to be an annoyance. Another issue with guides is when people follow them perfectly, while the guide might be good for one situation, it cannot apply to every singe one available.
In TA's section they say to get psi blades at 2, 12, 13, and 14. While this may legitimate in a lane where the other person is an easy kill, if you're against someone with a better base range the harass you are going to take is going to be insane. Another issue is a lot of guides are outdated and aren't often updated.
Look at PL, while radiance rushing might not always be the best option is certainly is the current meta. This guide advocates running a vanguard and soul ring, where a radiance becomes a luxury item.
Hell, Sniper's section, tells you to max Shrapnel before Headshot and Take Aim, since PRC was put into the game, and affects Headshot, I can see no reason to max Shrapnel over Headshot, and Take Aim is easily one of the best laning phase skills due to its range increase so that you can farm far more safely.
Better yet, the Lich section has a Vladimir's Offering in it. It can be used to help your melee teammates, but come on. Mine as well focus the Scythe of Vyse or etc.
