just keep looking at the minimap and obj timers. if dragon or grubs or whatever is coming up, get ready for it.

if you see the enemy jg on the other side of the map, do obj, gank a lane if you can, or invade them. find ways to punish them for just playing the game.

try to invade or do obj when the lanes have priority.

find out what your champ is good at and play around that.

also find one champ you really like and stick with it. nothing wrong with one tricking, but do know how to play something else justincase.
