There's no real rush to get ahead in Pokemon GO. Even if it starts to fade a little after its ludicrously fantastic launch, there are millions of people who will be just getting into the game over the weeks to come. Maybe you're one of them -- after all, the game just launched in Canada, and Japan is still waiting for it.
But while others may proceed at a leisurely pace to catch 'em all, let's assume that's not for you. If the thought of having other teams control the Gym near your house makes your blood boil, or you simply have dreams of becoming the very best (like no one ever was), you're going to need to level up faster.
