Round up a motley crew of engineers, designers, and project managers to tackle the behemoth of a project.
Make sure they're all wearing matching "I'd Rather Be Surfing" t-shirts to boost morale.
Decide which features to implement first, and which to save for "later" (read: never).
Don't be like that one guy who tries to do everything at once and ends up with a project that's a mess.
Write the code, but don't bother with things like "best practices" or "testing."
Just code, code, code, and hope for the best.
