Stay distance, use your Q to last hit, try to hit the minion at the same angle at their champion to poke! Only farm, only farm and only farm. Even if the enemy has 10% hp, it's likely that you still can't kill him because remember you are in Bronze, your jungle may not be as good as their jungle and you get baited! So be calm and collected!
Keep farming all game, till you are full items. Use R when someone is low, try to kill steal with your R2 and W and run. That juicy 300 gold is gonna be more helpful on you than your Bronze teammates!
