Lawn Care

Any suburbanites out there have any lawn care tips? Want to grow in the patchy spots, get rid of the weeds, and make the lawn healthier overall. When should I do it all, and in what order?
My lawn care:
Grab beer. Mow lawn. Put lawn mower away. Repeat once every week. (You can repeat the beer part more frequently)
Only advice, ignore whatever chadboy, if he posts, says.

I for one don't believe in letting the grass get nutrients, then it just has to be mowed more frequently.
