My typical game is usually grab-consolidate-expand.

In the first few years I try to grab a few (~10-12) key provinces either from rebels or in a small war if it's worth it.

Then for a while I try to build an economic/military base in these provinces, generally not acting agressively.

Then, around the time where my army is pushing the limits of my empire's financial capability, I start attacking. Usually on VH there's no need to go looking for enemies, and I take them out in the order they attack me.
