How to jg in bronze

So I see a lot of posts talking about junglers/how to jungle, and it does help. Let's be honest though, some of us are just bronze level and will never be able to do everything to make us a great jungler. So here is my small list of how to be a decent jungler in bronze in no particular order.

1. Ward: I'm always buying wards when I jg. I always get at least 1 scuttle crab my first clear. On my first back I try to get my jg item, a potion, and a ward. I also try to get at least one ward each back, and upgrade my trinket at level 9. I try to focus my wards around dragon and the lanes the enemy jg frequents the most.
2. Know your match up: Know who the jg match up favors. If it favors you invade, if it doesn't ward defensively. If I'm the stronger jg I will ward up their jungle and constantly pester them.
3. Pay attention to your lanes: is your top laner toxic? If so don't spend to much time helping him, because the majority of the time it will only hurt you. If one of your lanes is doing really well then help them a lot. Snowball the lane and you have a solid chance iof winning. This is unless they ask you to leave, then go help other lanes.

I know this list isn't perfect, but if you do these three things in bronze it will definitely help.
