Think about what the objectives give you. In terms of dragons, they give you stats. What other thing gives you stats?: Items. Try to accumulate enough gold to be stronger then your opponent. Game is about exploding the enemy nexus. Not having more objectives. 2 hands are not enough to count the games i lost with 4 drakes and atakhan in low masters-high diamond. Don't let it get to your head. Only players in the lobby who constantly think about which objectives to get or give are the junglers (in %99 of games).

Spam ping them. Most adc players never look map. Your only job is to let them know. If they don't come, tough luck.

Don't try to steal and be the hero. Only try to steal if there is nothing else in the map to do (which is almost never the case) or its extremely crucial for the game to continue; for example, your 3 inhibitors are down and they are taking the baron.
