Tips for jungle?

Your time is everything, don't spent your time trying to gank a bad lane.
don't spent your time walking to a bush and satying there for the rest of your life.
gank only when you see, OKAY NOW I'LL GOT THAT KILL
after getting a kill, farm the lane so the minions can reach the tower, the enemy loses XP, ur team do damage to the tower and your lanner can go base without any problem.
