How can you get better at Fortnite?

I'm a noob in Fortnite, how can I get better?

Train in Korea.

Try combat lab. There are bot grenades there. Simply collect weapons, grab a helicopter, fly over a city and throw out bot grenades (ATTENTION: There are friend's bot grenades and enemy bot grenades. Take the enemy's bot grenades), land and do your best against the bots. They act like real players. At Kampflabor you respawn too

Creative mode and play for kills in normal matches, regardless of whether you die.
