What's the best advice Present-Hiro could give Past-Hiro?

• When you stab Sylar at Kirby Plaza, MAKE SURE HE'S DEAD.

• Don't hook up with Yaeko. It'll only turn Kensei into a genocidal maniac.

• Don't open that damn safe. Ever.

• Don't try to outwit Mr. African Isaac unless you want a concussion.

• Don't go to India to fulfill a prophetic painting. Just...don't.
