Jungle Trouble Season 7

So out of all five roles, jungling has always been my worst. I was getting slowly better at it before the jungle changes, but now that things are so different, I feel like I'm back to step one. Yet apparently junglers are also super OP right now so clearly people have to know what they're doing. For the junglers who frequent the boards, do you have any tips on how to play in the new jungle? Who are some good champs to practice with to get better at clearing/ganking? What are some things I should and shouldn't be doing? Any and all tips would be appreciated!
