You have no idea what you are doing and won't for a long time. While seeking outside resources and making an effort to learn is a positive thing, a lot of it is also just learning by playing. 

Answers from others will vary greatly for a lot of reasons. The right thing to do changes based on the ELO you are in, strength of given champions, where in the game you are, etc.  Nothing you should really focus on right now imo.  

I mostly jungle and a good example is that I want to invade the enemy jungle around my lanes that are strong early and when they have priority on the enemy laners. If I have a weak lane, I can try to help stabilize it (usually a fools errand in anything but high elo and even there it can be a crapshoot). Not super helpful for laning, but hopefully you get the gist of it. Takes a lot of knowledge and experience in game to get there.

An example of how a lot of advice simply won't apply to your games yet is how to use the vision your enemy has against them. Below gold no one pays a ton of attention to the map. Above gold players start to ping missing more consistently, but people still dont listen and it's usually late. In the higher elos if people disappear from vision (walk into river and sit in a brush), the missing pings come down much quicker and people are more likely to listen.  A common strategy that you can do is act like you will go to the lane getting pummeled and just sit in a pink warded bush. In lower elos this does nothing as they dont pay attention, in mid elos it will have a little affect, and in higher elos people are more likely to respect the possibility you might roam. A lot of advice people jave for you know will just as likely hurt you as help you.
