How can I be a good top laner?

Go ham, tower dive and spam Ctrl+6, ward that bush, and if you get ganked, get a double kill.

• Take breaks
• Don't be toxic to other players, it doesn't help anyone
• Don't give up, anything can happen during a game
• Look up guides on youtube or watch streams of pro's
• Look at your map every 5 seconds (Words of Faker)

All I can think of right now ;)
